weird charging issue

[darkflare999]

Hey everyone I have a 94 v6 3.4 camaro and as the title states I have some kinda charging issue or power problem...While the car is running the voltage just drops little by little and won't return. Yes this may sound like a charging issue and I have tried 2 alternators and I have different batteries.

I had a high powered alt (220amps) hooked up with 2 yellow top optimas for years then this issue started..my perfect voltage used to be 13.2 v. Now it drops to 9-10v and my car stalls out sometimes because the fuel pump doesn't get enough power. I then tried the stock alt back and still the same problem. I tried changing the battery in my truck and the one up front in different combos to see if it was a battery issue but still nothing..

I should mention I had my alt exciter wire relocated to my ignition power because the primary wire from the gage to the alt was shorted.. Also in my opinion I think it maybe the starter drawing all the power...so let's here some suggestions plz!

Re: weird charging issue

Is the 9-10 volts with a volt meter, or the gauge on the dash? Mine with a good battery and 200 amp alt. and caspers voltage booster stays around 12 volts. I woud check grounds and do the big 3 wire upgrade also.

Re: weird charging issue

I have a power probe and got the reading from that..I never listened to the gauge cluster..and I do have the big 3 already..When it was charging good the cluster always read 10v even though I had 13.2..so after all that I don't pay attention to the cluster
