Question about 1997 Pontiac Sunfire
Charging system, I have 97 Pontiac Sunfire 2.4 liter SE I just bought the car from a friend. Here's my problem batteries keeping dying on me I thought I had a short somewhere or that something was connected wrong and was drawing a lot of power. one day i decided to pop the hood and really get dirty and figure out what was going on. Here's what I found. I have a voltage regulator mounted to the firewall, the alternator itself is jimmy rigged with lines 2 lines running from the inside the alternator where the brushes would be I suppose to the voltage regulator that's mounted to the firewall. I know this had to be the problem and I assumed that the alternator was shot. I took the alternator off and had it tested and it was shot. Now my problem is this because of the way it was hooked up which was 1 line from the battery to the back of the alternator and then it had 2 lines from inside the alternator run to the voltage regulator mounted on the firewall. Then from the voltage regulator mounted on the firewall those 2 lines ran from the firewall to the interior of the car somewhere underneath the driver side dash. Now that I have a new alternator I know that I cant connect it to the voltage regulator on the firewall because the new alternator actually works but now I'm lost as to whats suppose to connect to the harness connector on the alternator because I don't have any connector that fits within the engine compartment. I'm assuming that when they jimmy rigged the alternator they did away with the wiring harness. my question is this what else besides the main line battery to alternator connects to the alternator I'm referring to the harness connector that's has 4 pins ? reason I ask is because I intend to having the harness made I just need to know from the alternator to where ?
Some friend...... have a repair shop check it out and fix the wiring like its supposed to be. it going to be costly, more than just replacing the alt in the first place.
