Merc charging - I think I already know the answer to this....



Found out why my tacho wasn't working last night - only getting proper volts on one side of the rectifier input.

I am completely shooting in the dark with all fingers crossed here, and am pretty certian I know what the anwer is going to be, but does anyone know of any rectifier failure modes that cause an earth fault on one side but leaves the other "intact"?

I so can't be bothered taking the flywheel off....again!


On the assumption that the answer is "no", anyone got a charge coil for a Clamshell 50/60 lying around that they don't need?

Almost certainly the square rectifier I think in my manual there is a simple test for this with a multimeter

That gives me a slightly wamer feeling (I don't need to remove the flywheel to change the rectifier!)

Yep it.s the rectifier. Total short between one input and the heatsink.., which is of course screwed straight to the block...
