My 94 Deville is reading 18.1 volts and is showing battery volts high
JA: How many miles are on the car? Do you happen to have the wiring diagram?
Customer: 88764 miles yes I do
JA: Tell me a bit more about what's going on so he can help you best.
Customer: Everything was fine, when I got back to my car from the zoo it started with this reading and problem.
JA: Are you hoping to fix this yourself?
Customer: Yes I am
JA: Great! What have you tried so far?
Customer: I'm guessing it's the alternator
but I've seen other people have easy fixes forfor it
JA: Is there anything else important you think the Cadillac Mechanic should know about your Cadillac?
Customer: It's been sitting for 3 to 4 months that's all info on the car
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Cadillac Mechanic about your situation and then connect you two.
