I feel I have

Have you checked the fusible links?

Customer: replied 10 months ago.
Where is that at

in the engine compartment fuse box.

Customer: replied 10 months ago.
All look good in there

check all the connection for corrosion and tightness. at the battery terminals. at the alternator. check the main battery ground where it bolts to the engine. check the other battery ground also.

check the connector that plugs into the alternator. make sure the wiring insnt damaged and the connector isnt loose.

Customer: replied 10 months ago.
There is no ground wire from negative battery post to engine

there has to be. thats the main ground

it might be connected to the transmission instead.

Customer: replied 10 months ago.
The only lead coming off negative terminal goes to the body next to the fuserver box

how long have you had the vehicle and has any other work been done to it lately?. also if you look at the print ive attached. there is a main ground wire that need to go to the engine. its the main reason you are having the problem

Customer: replied 10 months ago.
Well it's my step sons car and he had transmission problemso took it to a mec in the city and now this is about 2 months after

well you need to go buy a negative battery cable that goes from the battery to the engine block. and also need to check the continuity of the wiring from the alternator to the relay box and to the fuse panel inside the passenger compartment that goes to the pre excitation resistor

Customer: replied 10 months ago.
pre excitation resistor
What is this
Customer: replied 10 months ago.
How do I check continuity

drop the power down to a manageable operable level. lets just install the ground cable before we worry about the continuity.

Customer: replied 10 months ago.
I did a jumper wire

it needs to be a large gauge cable securely fastened at the battery and to the engine block

Customer: replied 10 months ago.
Lol ok fine I'll wait one more day,


any luck?

Customer: replied 10 months ago.
I got the wire didn't have time to put it on
