ok, my Battery guage the second I hit the TRIM button to put it up or down it goes to 5-8 then will go back to 13 I think it should be at 14.7 ??

Any idea why it is doing this.. weak battery?? Bad Alternator?

23 powerquest single SBC

Thanks,

Steve

Mine does the same thing--------- for the last 9 yrs.

I have found a new strong battery does keep the volt meter much more stable.

Mine runs a volt or two low also. The trim is a big draw when you hit it.
