Odd Voltage drop.

[locomc 10+ year member]

Hey. I'm having a problem. My voltmeter on my dash has registered a massive voltage drop. Everything on my system runs fine, but I believe that the voltage drop is real and not the effect of a busted guage. I think it is my alternator that's going, but I decided it would be a very good idea to consult others. Any ideas?

The alternator is probably correct. Alternators like to go when spring turns to summer--I just replaced mine thursday. And, alternators do have a way of going bad gradually, not instantly (anywhere from a day to three days).

Your local auto parts store should do a test on it for you for free. Do it now before you get stuck on the highway.

Nope. I know it's not the ground. I have 2 8g and 1 2g ground coming off of my batteries. I also have two Optimas so I know it's not them either.

OH, nope. All three of those wires go to separate grounds. So i'm set. I'm getting the Ol' alternator replaced tomorrow. Thanks for the advie amigos.
