hi my 1997 chevy blazer ls 4wd hit a tree on the ice and since then has had an electrical issue and turns but wont fire. I noticed that of the 3 cables that hookup to the negative on the battery, one of the 2 smaller ones had a break and isnt grounded. The car crashed on the passenger fender so im wondering if this is my problem. I believe this is the g105. is this my issue?

 

Yes it is possible that this is the problem. Try connecting it back to the negative on the battery to see if it solves the problem.

 

It's connected to the negative on the battery but it's just not grounded and to get to g105 it will involve removing the radiator. Do you think it would be just as good to ground it in a different yet similar spot?

 

It maybe your alternator.Have someone test it for you.If and when a alternator goes out it?your motor won`t turn over.

 

cars with faulty alternators will start and run as long as the battery is charged

for testing, run a temporary grd to the engine block. the alternator is case grounded.
