Hi! Anyone knows how the fuel reserve lamp on the '98 SH works?
The other day I ran out of gas because the fuel lamp did not turn on, it was working fine before. I have checked the connections and it was ok, I have also tried to test the fuel lamp terminal going to the wiring harness by shorting it with a piece of wire and the lamp turned on. Tried to drain the tank again to make sure it works but it wont turn on even if the tank is already empty.
Anyone who know how to remedy this problem? Your help will be greatly appreciated, Thanks!! :-D

 

I guess you'd have to hook up a 12V source to the connector going to the cluster. If it comes on then the problem is the sensor in the tank. If it doesn't come on then the problem is in the cluster, possibly the LED burned out.

 

Hi Greg! I have traced the wiring connector from the tank sensor going to the cluster. When I disconnect the plug and take the connector going to the cluster and put a jumper on it the fuel lamp will turn on while the ignition is on, so I'm guessing that the sensor is bad. Is there a way to test the sensor? And if it is at fault is there a way to repair it? thanks!

 

Tricky to test for some reason. I set it up on the bench, to check it out as when I changed tanks it appeared to not work for some reason.

So I did everything I could to get it to work, and no go. So I thought I would re-install it until I could get a replacement. After I rode the bike down the road it started working!!!

So it would seem that in my case, it needed a period of time for it to start working, like it was on a time delay. I don't understand it, maybe it was just one of those freak things.

Just letting you know, so you don't end up doing something similar.

 

Oh yeah, it is on a time delay. This prevents the thing from coming on and off rapidly while the tank is just above and below the 3.2 gallons.

 

Ah-hah!!!!

Couldn't see anything that would activate this when I was looking at it. Is it controlled by the ECU Greg?

 

I think not, as the wiring diagram shows only wiring from the sensor to the indicator, with the associated grounds.

 

tried to remove all of the fuel again and wait for the lamp to turn on (ignition turned on) waited for more than 20 minutes and it still didn't light up, Any of you guys had an experience of fixing or replacing the sensor?

 

I have the same problem. I gave up, and just put gas in every 75 miles.
I did take my sensor off my tank all the way, but I did not let it dry out or anything.
