Re: Just Fried a New Coil with my Mercotronic

if 7.5 volts is a critical point you may want to consider a 9 or 12 volts supply connected to one or more of these "regulators" wired in parallel to give you a piss flat 7.5 volts

(going 2 in parallel will double the amps capacity) just join the identical legs …. two to 12volts two to common ground and the last two will provide flat 7.5 volts.

I have used a similar model to stabilize my humminbird sounder which was freaking out and shutting down with my Merc 45 high voltages charging my battery with over16v at WOT

connect your "new external 7.5v supply " to the internal battery terminal and you are good to go .

just disconnect the 12volts supply when done. mount the chips on a small aluminum plate to dissipate the heat while in use.

Never had a shutdown on my humminbird after I added the regulator under my console.
