So..not getting any any love from the Troglodyte at the alt shop. I'm done with them. When I took it in, I explained my Alt light flashing symptom and asked specifically that they replace the diode trio, rectifier, regulator etc..as well as the usual bearings, brushes and anything else that needs doing. I was surprised when he only asked me for $80 as 9 years ago his brother charged me $140. He assured me it was all done. OK then, hook it back up, Alt output is 14.2V, which I'm told is within spec although the volt meter shows a slightly lower reading. The Alt 2 light now flashes even more..like its doing morse-code at idle and lower throttle settings. Not happy about this. Took the truck back, let them test it. Its good they say, the flashing light is "something they sometimes do". Appears to have a new regulator and rectifier, from what I can see through the case.
Spoke to the tech guy in back, he just said there wasn't anything wrong with the alt when I brought it in, besides the bearings. Discussed the diode trio..he was adamant it can't be the cause of the flashing light. Asked them if they replaced it, just got a blank look. Maybe they put the wrong parts in or they're faulty. So, I'll have to do this myself. Instead of ordering a kit, I would like to just buy the few component I'll need;diode trio, regulator and rectifier. Anyone have the exact part numbers for these? And are our rectifiers positive ground or negative?
