I installed a 3G single wire alternator and I noticed that my alternator light doesn't light up when I turn the key on. I have double checked the installation and every thing is ok. so if my alternator bulb burnt, where is the best place to tie in resister. Can I tie the resister in line from the Alternator "I" wire. The instructions show at bulb location. second question is what kind of resister should I buy.?
