Was out riding and after an old haunt fantastic road - moto just died at stop sign.

No electrics - checked all fuses - Then jumped started it - thankfully I was on a hill.

Was running a bit rough. Died again about 1 mile from casa - and jumped it again on a slight downhill - Phew!

Also while I was riding home the tac & speedo - was flashing like it was normal and then nada.

Came home & hooked up to Battery Tender & tender is slowly flashing red / green. (it never does that)

Battery is old - but hasn't had a problem starting before.

terminals were tight.

Regular / Rectifier - is a Mosfet and about 8 yrs old.

Thoughts??

And She was looking so good - washed & waxed her.

 

What does flashing red/green indicate according to the tender?

Just a guess, but methinks your battery is shot.

 

When battery tender is on normally - Red stays constant on, green may be on at same time - then when fully charged its green - but NEVER flashes

 

The battery? as VTR1000F suggested. Check the voltage, off, on, during starting, while running. Could be the R/R also. Also check the connector under the seat that goes to the stator.

 

If the battery is old, throw a new one at it. And just because the R/R is mosfet, doesn't mean it can't fail. I'd say unlikely, but not impossible.

 

My Deltran Battery Tender starts out solid red light and the green starts flashing when battery is 80% charged and then goes to solid green and red light off when fully charged and in float mode.

 

OK got a multimeter and some time today to test

Ignition off: battery is ranging from 10.5 to 12.6

Ignition on: (and still no info on dashboard - totally blank - except clock that keeps resetting) reads. . 20

I'm not an electrical engineer but I do play one on TV.

Will check connections to all electronics

Any advice?

 

What do you mean it's ranging from 10.5 to 12.6? Should be steady within, maybe, a tenth of a volt. It's possible the battery is bad and when you put a load on it by switching the ignition on, it basically craps out. Can you jump it from another bike or car to confirm or rule out the battery?

Again, methinks your battery is shot.

 

Reads .20v?
If that’s the case, battery is junk. As above, it really shouldn’t “range” much when you switch the ignition on.

 

This is what she looks like....

How do I know if the Regular / Rectifier went bad?

I've checked all fuses - everything looks OK in terms of connectors to various items

 

OK

 

What? Why do you believe him? He's a comic book character. At least, I'm a motorcycle.

 

I would have liked to see what happened with the jump start idea. Battery should definitely not dissipate with ignition switched on.



(nothing comical here)

 

Thanks Guys

Got new battery from Advanced Auto - $116. (Guys said car batteries are $200 for good ones now - WTF! - Thanks FJB)

So I checked my written records (as all mine were lost due to Honda killing the moto owners online) Battery was a Scorpion from Battery Plus in 2014!!! Who here has gotten 8 yrs from a moto battery? For sure the longest for me. Battery Tender used on/ off all year round.

I'm still going to check Stator to see what its pushing out - a buddy of mine said it should read about 70 between terminals.

And just throw Buckeye Nuts at Wolverines they run away fast.

 

And read your voltage after start. Should be about 14.4.

Buck the fvckeyes.

 

Follow up:

Just got around to checking the stator yesterday.

Everything seems fine - checked with moto off then on and all #s between the 3 terminals were the same.

Son was supposed to use it today to ride with pirates from his work but thought it was a better idea to drinking last night and then got into an altercation.... He's fine - Dad rescued him @ 0500. (had my 9 on me - ya never know...)

So I'll go riding instead

Stay Safe

And readings running then at rest?

Did the guages come on correctly?

And ride results.

Coincidentally my 7 year old Motobat died and I have another ready to install and fire Old Red up for the first time this year.

Due to my rotator cuff surgery in March and complications (confirmed yesterday doc has to go back in and try again) I only got out on Young Red a week ago for the first time in 7 months. Longest ive not ridden in 50 years!!! It's been hell.

 

Update - No Bueno

Went to RTW last week & started - then while warming up in driveway, stalled (not uncommon when 1st starting) then the dash went blank. Then came back, but wouldn't start.

So, me tinks I have a loose ground?

Was going to look at today but worked last night - too tired, this week I need to sort out.

Open to suggestions

Thanks

 

Jeez I'm bad - its been a year since this problem - was going to take apart again to test, but new battery is dead from sitting since last year - just ordered a new Mosfet R/R on ebay. Should have it by weekend.

install it and probably jump it - then put on battery tender. Been too long without riding - I need to ride to stablize mental health....

 

I think the R/R swap and a good battery will solve it. (Fingers crossed)

And I agree on the mental health thing. I’ve been commuting a lot on 2 wheels which is good but no group rides. The fellas I ride with became sort of political extremists, which I just don’t want to be around so not raking up many miles
lately.

Let us know how you make out with the mosfet.

 

Hey the media has turned this country into this ******* mess along with inept politicians.

I can't watch the news channels - I just get upset. I live my life like I always have - treat everyone with respect until they lose it.

Surround yourself with people that bring you UP in life and drop the ones that bring you down.

I'll keep ya posted on Hawk

And maybe I'll get down to the Getty and u show me the roads....

 

Anytime!

 

Yep the 8 yr old Mosfet R/R was the culprit.

Installed new one yesterday and put on Tender

All good!!!

But some bad mojo - my brother in Denver was just cut off on his old Connie and hit crazy broad doing an illegal U turn in front of him. Thankfully he's pretty much ok - thumb is fcuked on one of his hands.

Watch out while riding kids

 

Dang, she's a noisy one!

Sucks for brother. Been a ton of years but me and a friend had a lady do a left in front of us that caused a huge wreck. Hope he can recover quickly.

 

Hawk is all good

Rode about 100 miles yesterday before the heavy rain - I got caught in some of it but not too bad.

Felt great to ride again

My breakfast stop at amigos casa

 

Hello I'm new to the forum and want to help future proof for less maintenance for that issue. For me on the regulator rectifier I stopped using the plugs that connect them together because at the plug it does cause a resistance 90% of the time which causes it to be burnt on certain spade connectors and shortens the life of rectifier. this is what I do.

​​​​​​If you don't have one look online for a soldering iron station and buy a fat tip for it for more heat and better apply of the solder. I highly recommend Weller it should be around $65.00 or a little more its worth the money and you can buy other tips for other applications. Make sure that soldering station has a variable **** on the base that goes from 1 to 5 or higher. Set that **** on 5. Also that station will pay itself of for future soldering on other wires on the bike and other projects as well.
Take a picture of the wires to make sure they are in the correct order before cutting the wires or do one at a time.
First cut the wires on both sides of the plug.
Tin both wires get some heat shrink and put it on one side of the wire that has a good distance from the solder joint or the heat shrink will shrink before you have a chance to slip it over your joint.
Solder both same colored wires to each other however you will have 3 wires on the left side and right of that plug those are the stator wires all 3 will be white or yellow. it does not matter if they are in order because those are all the same. if you aren't sure? Leave those uncut and do all the other ones first then do those wires one at a time instead. those wires are A/C before being converted to D/C.
try to make sure the wires you are soldering are about 1/4 inch or just a little more to be on the safe side but not to much or the heat shrink won't go over it. solder the wires side by side for better connection and make sure you don't have a rogue wire standing out or it will poke out of the heat shrink and possibly cause a short. If you have any sharp pokers on that joint cut that point off or file it down the best you can. I use a little extra wire of the same gauge to make the wire a little longer in between them to have better space for the heat shrink and to move them to a better spot so it's not stressing the tension and can be tide up out of the way for wire management. I have done this to all my bikes and I have yet to have any issues having to replace my rectifier. For instance my VFR had 35.000 miles on it and 2 days later it wouldn't start so I charged the battery then did the procedure on it? So far its still working with no issues when I had it for 9 years and had 97.000 miles on it this will work on all bikes and prolongs it and less to worry about.
hope this helps.
sorry if this is so long I just wanted to be extremely thorough.
