Burning through alternators
Good afternoon guys - this is my first post here, looks like a lot of you guys are pretty knowledgeable on these Turbo Era Dodges. This is my first G-car. Im a huge C-Body Mopar guy and all of my knowledge of cars is limited to 65-73 Chrysler products.
The car is an ‘86 Daytona Turbo Z. I bought it last Saturday. The car has 50,100 miles on it. I bought it from the owner in Somersworth, NH who had just drove the car through the latest HotRod Power Tour last month. For him the car drove perfect.
After I bought the car, I drove the car from NH down to NC a 900+ mile journey. About 400 miles in, around Baltimore, I was pacing a ‘19 Charger (I know bad idea) and I guess for a moment when I hit the car at WOT I felt the turbo cut out and the alternator stopped charging.
There was a visible loss of power for a few minutes, which then after it returned, and the alternator charging returned. Sometime after that In the next 50 miles the alternator stopped charging and the car only ran off the battery. I made it until about the NC line, about 700 miles into the journey when the car completely lost all power. Thankfully I had a friend in-trace behind and was able to charge the car.
I switched the power module when I got home with another (not new) to see if it was the voltage regulator and it made no difference. I jiggled a few wires and connectors to see if it was a loose connection. Finally decided to change the alternator, bought one from advanced auto and BOOM it worked perfectly. It was the original so I didn’t give it much thought. This was Thursday.
I took the car for a a 160 mile drive, and about 100 miles in on the return trip - alternator stopped charging. Made it back home, checked the multimeter and the output is at 11.76V
So now it’s been about 7 days and I’ve gone through 2 Alternators. I know sometimes even new alternators and be crap especially if their made out of Chinesium but really? What else should I be looked for? A short?
I’m not too electrically savvy so assume that I know NOTHING.
Thanks in advance guys,
