Yesterday was big smiles thanks to help from this fine site and it's many knowledgeable folks I got another rectifier and after meticulously cleaning every ground and tracing and inspecting all the wiring it actually worked and nothing else burned up. The volt gauge gives a delightful twitch as the rmps go up. So after having it run for more than a few minutes I noticed the left side of the engine was much hotter than the right to the point I could not hold my hand on it whereas the other was only warm. Is this normal? Is it possible that chunks of the old disintegrated impeller may be stuck in some passage. I've never split open a power head to know how the water flows through the case
