Hello All.

I am getting less than ideal voltage across my battery terminals when fully warmed up across all RPM.

I am getting around 13.3-13.7 at the terminals with just stock headlights on, no accessories other than the voltage meter.

I am getting higher voltage when I test from the voltage R/R, around 14.3. Is it normal to have such a large discrepancy when testing from these two locations?

Thanks,

 

It's a common issue. Here ya go:

You can use your voltmeter to isolate any section of wiring that may be causing a voltage drop. Just touch the probes on either end of a section of suspected wiring under load and see if there is a voltage indicated. I would like to see LESS than 50 mV-if it reads higher then you have something(wiring, connector, etc) that has a high resistance. Use the probes to isolate where the voltage drop is located and repair that fault.

 

Thanks for the replies.

I soldered 12 gauge wire to the ground wire that runs to the rectifier / regulator and grounded it to the starter ground bolt. I now have about 13.2 at idle and 14.1 -14.2 revving.

Would the lack of good grounding cause the OEM R/R to fail prematurely? I had to swap out for a Ricks motorsports R/R as my OEM was outputting zero voltage. Stator passed all checks.

Thanks again.
