Alternator

Post by GBKid » Sun Jul 10, 2016 7:20 am



Three weeks ago I installed a set of Show Chrome driving lights on my '89 GL 1500 (featured in the monthly newsletter if you missed it on my forum post at that time). Well this isn't about the driving lights per se, they are a great product. My alternator has expired coincidentally on the heels of installing the driving lights. Now my bike has 74,000 miles on it and the only other electrical draws are the stock equipment, and my add on Garmin GPS and an I-Pod. My question is could the addition of the driving lights put extra stress on the alternator enough to cause it to fail suddenly? Or is it just simply a coincidence?

If the draw from new lights isn't that much I would bet just coincidence. Had a pick once that I put a set of aircraft landing lights on and they would trip the breaker in the alternator and after switching the lights off the alternator would reset.

Would the lights put any draw on the alternator at all? Don't they just draw from the battery and the alternator would simply recharge the battery at a constant load? Gotta admit that I'm way out of my depth when it comes to bike or automotive electrical systems.

I found out from Show Chrome today the driving lights draw only 8 amps so that amount is insignificant and the stock 40 amp alternator should handle that without a problem. My alternator just simply died. The bike has 74,000 plus miles on it and is 26 years old, so no surprise. My diagnoses determined it's the alternator. I ordered a replacement and I will have it up and running again by the weekend.
