Re: Welding w/ Battery connected, now it won\'t start

Check your battery cables and your ground.
Welding current will find any weak connections.

With everything hooked up...
Take a 16 Ga. wire (or larger) and connect one end to the positive side of the battery, and the other to the small terminal on the starter solenoid marked 'S'.
Be prepared for the engine to crank! Have it out of gear and the E-brake set.

If the engine cranks, it's not the battery, battery cables starter solenoid or your starter.

Check to see if you have power to the wire that's supposed to hook up the 'S' terminal when the key switch is turned to 'Start'.
You can use a light or a buzzer with one side plugged into the wire, and the other grounded if you are working alone.

If you don't, check fusible links and fuses.

Get back here with the results and we'll go from there.

You can try jumping it, but that won't find your problem, just bypass the symptom.

Re: Welding w/ Battery connected, now it won\'t start

It doesn't matter...
If you were welding with reverse polarity, the introduction of high amperage and/or voltage current to the vehicle ground may have nuked the diodes in the alternator, and the alternator is sucking your battery dry.

You may have 'Hot Charged' the battery with AC or DC voltage... Hot charged it to death...

You may have started to nuke the battery, or some other component, but the bad ground let go and saved the components...

It may just be a coincidence that the problem showed it's self now...

You won't know until you charge and load test the battery, and jump over the solenoid...
If it starts once, and won't start in the morning, start looking VERY closely at your battery and alternator.
Both should ALWAYS BE UNHOOKED BEFORE WELDING ON ANYTHING!

BTW?
What kind of welding were you doing, ?
MIG, TIG, Stick?
Electrode positive or negative?
Stick welders are notoriously hard on batteries, and MIG welders are notoriously hard on alternator rectifiers...

NOPE!
Proper eye protection is always First and Formost...

It's hard to wheel,.... or look at Playboys..... or anything else when you are blind...

The thought of a previously installed alarm getting fried during welding would have driven me crazy for DAYS!!!! /wwwthreads_images/icons/mad.gif

Glad to hear you are up and running!
