OK. I used search and I think I know the answer. It has to do with the "generator" light staying on with the key off. The light works as intended prior to start and goes out with the engine running.
Auto climate control:
OFF ECON LOW AUTO HI BILEVEL DEFROST
gen light faint faint bright bright bright bright bright
fan mtr. on on off off off off off
Which of my climate controls are bad?
Thanks, Ed
Coul be a bad diode in the alternator.
Does anyone know if the alternators are one piece (i.e. voltage rectifier built in) of if you can replace the voltage rectifier independent of the alternator?
Thanks,
Ed
Ed,
I think I mentioned that you have a bad alternator, as well as someone else.
It's easy to get to and replace, easy to find as a commonly available part. It has an internal regulator.
They symptom exhibited indicates a bad diode, allowing current to pass to ground, hence the light, and battery drain.
Should be about 225.00 done by a mechanic or $125.00 done by you.
Good Luck,
Brian
PS... I'll buy your car in a heartbeat if you get fed up with your electrical problems.
Hi Brian,
OK, I'll accept the alternator as having a bad diode because as you point out it's a relatively inexpensive fix. And "my" mechanic thinks so as well, saying it's hot around the negative terminal. There may still be something with the auto climate controls but first things first. Before wanting to buy the car, you should know that I got taken. By that I mean the seller did a quickie spray job on engine and engine compartment, at least things that showed in the photos. Anyway after putting the car on the lift and having it gone over I'm dropping over $4K to make it driveable. All new fluids, gaskets, hoses, belts, filters, shocks, some suspension pieces, etc. Admittedly, much of that is labor but still.... If I ever buy another car sight unseen I should be shot.
Regards,
Ed
Ed,
No one should buy a car sight unseen unless you are comfortable that the seller is representing the car 100% honestly.
I have sold cars on ebay but provided full disclosure and encouraged bidders to have the car looked by someone in a club or an inspection service.
I also inspect cars and handle complete transactions for foreign buyers. In the past I have negotiated deals on some expensive Classics and muscle cars, handled all finances, and delivered cars to the port for export.
It's too bad you got "taken" but, in my opinion, these H & E Le Cabriolet's are worth sorting out and getting right. Especially a 79, which mechanically was one of the best years for Cadillac.
Good luck,
Brian
I say again and again, look at these cars first, as mentioned by 76Eldo. I do appraisals around upstate area of N.E. and most are misrepresented out of ignorance on the sellers part rather than fraud. Forget the pics and claims, receipts and documents are required to prove recent repairs.
