I need help on fixing my electro harmonix vintage mole.Today i had one of the ground wire soldier back in place.Okay every thing was cool then but when i went to plugged it into one of my other pedals.No sound came out.I figured the battery was dead so i kept on playing a few minutes later.I picked up the mole was so hot that one of the screws burnt me.So i looked around on the internet to see if it was not wired right.and every thing looked fine.The guy that soldier my mole solider the ground wire to the knob.Instead of the switch i didn’t know if that had something to do with it or not or is there a certain way that these have to be hooked up .Can some who tell me if they have ever had this problem before or what could have caused it to get this hot like that :doh:
The black wire is generally soldered to the pot so that’s not the problem. It sounds like something’s shorting out your battery when it’s assembled.
It is such a simple circuit that even with a slightly better than basic electronics background you should have the problem solved in a short time. Try using the Mole without the back cover attached. Does it work? Then you are shorting something to the ‘chassis’ as you reassemble the unit. If not, then you have a soldering problem or a resistor lead is bent over and shorting the battery B+ to the common ground case (where the B- is connected to). Should be simple, but that’s just my 2¢, so always remember what you paid for this advice.
