So the good news is that I managed to get the new engine started today. She fired right up after a crank or two and ran great!! First time in 2 years...
Then, I noticed the alternator light was on -RED. Then I noticed a bunch of smoke from the engine bay. Turned her off and...The red wire from the starter to the alternator was red hot and burning...it burnt all the way to the alternator from the starter....... The battery was also making strange noises....and was very warm When I got the engine the harness was already connected. I connected the longer end to the starter. and also plugged it in to the relay board     Sounds like something wasn't connected right? Perhaps the red wire wasn't connected correctly to the alternator? |

So I managed to get the alternator out..
As you can see, there was a short between the SIDE of the nut and the alternator cover plate. See straight edge of cover plate. The cover plate then also shorted against the engine itself. What I can't figure out is why? One option is that it looks like the nut was too wide? It doesn't look too long and it shorted to the side , not the top. The second option is that perhaps the cover was put on incorrectly? You can see that the inside of the cover is mostly rounded - but then has a square side. Its the square side that shorted. But the cover has to point in the right direction for the rubber sleeve (for cooling) to attach to. So it seems it can only go on one way? Not sure how to solve this…Ideas? This was all assembled when the engine was delivered. and not sure if the alternator still works..       |
