Well the other night, I was driving down the freeway when all of a sudden, I notice a loss of power....like a small chug. Its just a little teeny kick but then I see my check engine light on and look in my rear view mirror to see in horror, sparks coming out the back of my precious baby. Well......the battery cable had melted through the heat shield under the exhaust manifold and it was sparkin up the place. (a paperclip now holds my car "together" ) So here is my question, I noticed then when I would feel a power drop, that my Tach would suddenly work, and it has never worked to my knowledge. Would somehow when the batter hit the metal, grounded something and made it start to work? It would only work for less than a second at most, then drop back to 0, but it worked somehow. Also, a little FYI on my car. My exhaust manifold in the past has heated up and melted plugs and connectors in the area around it....possibly scrambling some connections (don't know if this'll help with a conclusion, but ya never know). Thanks.

I would look to see how well your tach filter is attached. I would guess that in the past you had no gound to the filter and now you do (at least some times). The filter on my 86 se 2m6 is mounted on a stud right next to the headers. The heat may have caused the stud to swell and make ground contact. I know on mine the heat had caused the stud to work loose and I was having the tach jump around as the ground came and went.

Just my two cents worth.

On my Duke the tack filter is bolted, with a "U" bracket to the bellhousing. On a different note it doesn't seem right to have an exhaust so hot that it melts things around it. I know the exhaust gets plenty hot and will melt wires it they touch it. Have you looked at your engine when it is running in the dark of the night. I know it sounds odd the way I said it. Others report vacuum leaks and clogged cats as causing headers to glow faintly red to cherry red. You didn't mention anything about a "light" show, but it is something to think about.
I found an intemittent bucking and stumbling problem caused by a shorting battery cable on a Duke. I couldn't figure it out until I was working on a fan belt and bumped the battery cable. Saw the sparks and solved a problem. Good luck
