Hello!

Did you still need help?

Have you checked the inputs to the back of the alternator?
Customer: replied 3 years ago.

tested wiring to alternator. had alternator tested off of vehicle. I understand that off vehicle only tests alt not computer inputs. this is where I believe problem is sounds like I have a shorted system because of blowing meter fuse

Expert:  Amedee replied 3 years ago.
Ok.. there are three wires going to the back of the alternator. All three need to have power to them with the key on and engine running. CHances are you just have a blown fuse. By checking these wires for power, we will know which fuse to check. Here is a wiring diagram.

THE ONLY FUSE THAT IS BAD IS METER # XXXXX KEEPS BLOWING I AM TRYING TO FIGURE OUT WHERE A SHORT MIGHT BE IN THE CIRCUIT
Expert:  Amedee replied 3 years ago.
Does this fuse blow if you disconnect the alternator and start the vehicle?
Customer: replied 3 years ago.

I HAVE NOT I WILL TRY THAT AND SEE WHAT HAPPENS. PROBABLY WONT BE UNTIL MONDAY, THANK YOU FOR YOUR HELP SO FAR. ANY OTHER AREAS I SHOULD LOOK AT. THANK YOU BOB

Expert:  Amedee replied 3 years ago.
YES! If the fuse continues to blow with the alternator dissconencted, see if the battery light comes on with the key on. If not, you might just have a wiring issue going on here.

INSTRUMENT PANEL DOES NOT WORK. THIS WAS ONE THING THAT QUIT WORKING WHEN CUSTOMER HOOKED UP BATTERY CABLES BACKWARDS. I HAVE REPLACED PANEL.
Expert:  Amedee replied 3 years ago.
Ok.. one good test we can do is disconnect the instrument panel and turn the key on and see if the fuse continues to blow
