Re: Just Fried a New Coil with my Mercotronic

[oltimer]

quote FrankR:

Is the Merc tronic still working on other coils? Just guessing, I suppose it might be possible that it supplied a constant voltage to the coil and overheated it. But one would think you would have seen it smoking before that.

I have been using my model 98 Merc-O-Tronic for 30 years, and am leaning to what Frank has quoted. The 7 volt battery for coils, and wall plug in electricity for the condensers is "my unit". I am also wondering about the ground connections in your unit Kevin? Check them very close.
