Tach fritzing

Tach fritzing
So this is a strange cause and effect. I installed a brand new battery and in the next few days my tach has begun to not work intermittently. Then my digital thermometer.
These could be unrelated but could a slightly larger battery (YTX 14BS) do this? Seems unlikely or unrelated but has anyone had this happen before I start tracing wires?
Seems too coincidental to be a coincidence.

R/R is recently replaced and I have 2 voltage meters that are reading good charge rates. I will double check its connections now that you mention it and put an outside voltmeter to check.

Update: Voltage is 13.2 standing and 15.7-15.8 running measured across battery.
That sounds too high to me.
UPDATE 2 I swapped on my backup RR (also an R1 unit) and the running voltage went to 16.5-16.6.
BUT, the tach came back on so at least I can (sorta) rule out bad connnections.
The different volts could easily be due to me sanding the contacts when re-installing the ground.
That sounds too high to me.

Yeah, kind of like when I ask my wife where my glasses are when they are on my head.
I still think its just the clean ground wire that did it. Still want to do that free ground upgrade mod.

Well, sorta. That reading is with an actual multimeter.
I have 2 other voltmeters on the bike and they are reading around 14's. I am going to do some tinkering tomorrow to get a better sense.
I don't love the idea of a true 16volts, but don't think it is. Will try other meters I have.

16+ volts is in the destroy 12VDC components range
You either have a bad R/R if you really are getting 16v DC, OR you have a bad meter
