EMG 18V Mod on an LTD EC1000 Delux

Gave it ago but did not work out. I am pretty sure the batteries were set up correctly. Ammeter gave around 17V of current runnning through but then when plugged in to the guitar I would get no sound. 9V still works fine but could not get the 18V to work?

2nd Battery is probably dead/dying

Are they rechargeables? if so they're only likely to be about 8.5 volts

Actually looking at your wiring you've done it wrong, the red and black wires going into the guitar need to be swapped

Are you sure? The diagram you supplied has the coloring wrong for + and - at the first battery snap.



*edit*
Actually, colours are right.. but the symbols are wrong. So yeah that means you need to switch them as JB said.

Symbols are right too It has to be reversed since you're clicking the two connectors together

I guess. They are correct by implication. But not if you treat it as a stand alone unit.
If the battery snap has symbols stamped on it, they won't match.


Given that it is a sketch for 'paint by number' electricians, you'd expect it to show what the person will see.
It's not exactly an accurate schematic.
