Dodgy generator voltage regulator repair

etpm · 2017-11-15T18:56:56+00:00

The voltage from my generator drooped so much that a 3500 watt generator would no longer start a 1/4 hp motor. So I opened up the back of the generator and removed the voltage regulator so I could see the part number. Upon removal I see the ubiquitous bulged electrolytic capacitor. All the electronics are are potted into the reg case but the bad cap protrudes from the potting compound by about 5/8". Today I ordered a new reg but I am thinking that since the bad cap sticks up so far why not just remove the contents of the cap and peel the can out of the potting compound, thereby exposing the cap leads. Then just solder a new cap to the old leads or even directly to the circuit board if I can get to it. I think that I will end needing to solder a couple wires to the old leads and then solder the cap to the wires though. If this turns out to be the case will having the cap connected to wires that may end up being about 6 inches long be a problem? The cap in question is 220 MFD 250 volt. I will be replacing it with one that has a higher voltage rating. Eric

Don't worry. If it does happen, you'll be the last person to notice.
