i feel your pain bro.

I spend about 2k in a week and a half........all when my business slows to a crawl. Good times!

You could have just a loose connection, or a bad alt..check connections.

alternator is a cool 340 bucks.

Have you had your electrical system diagnosed? I would have to say that the batteries, starter, and alternator all going bad in 1 week is kinda impossible. I would have the alternator tested. If you have already changed the batteries and starter than no need in having to worry about that it is already water under the bridge. Get it tested so you are not wasting your money.JJ

You need to check it before you start throwing parts at it. If you don't know how we can help you.

i had the alt checked, it was putting out 65 amp max, i replaced this now.... lets see how long this lasts

Those auto parts stores tests are not 100%. have you checked the charging voltage at the batteries under load?

[harleycjm1]

i am now reading 13.4 under load for voltage insead of 10.1-9.8

Ok. Was that on the truck or on the bench? If was on the bench make sure that you check it on the truck. If that is the voltage on the truck then you should be fine. Just to be clear when I say under load that means you turn everything in your truck that you can on from windshield wipers to door lights.

its what my tuner said voltage was whn everything was on, including the light bar and siren, which the neighbors really ejoyed!!!
