What is this and what does it do?
(OP)
Hi, I am not an engineer but a volunteer for a spanish ONG in Madrid. we have a 15kw generator" Changfa Chinese clone". The other day I accidentally reconnected the battery the wrong way and burnt out the wires for the starter circuit. we replaced the wires and it now starts ok and generates current. There was one burnt out wire which goes what i think is a "rectifier" or "regulator"
We disconnected it and the genset still generates current.
Here is a photo of it it is the red wire that is now burnt out the green ones are ok.

Not so sure about it, but a couple of cent's worth.
Check the battery and see if it is on its way down.

Half full - Half empty? I don't mind. It's what in it that counts.

The cheapest fix may be a small trickle charger powered from the generator to charge the battery. That is how the battery is now charged on my gen-set, pending proper repairs. grin

If the diodes are damaged, Then the module may be consuming current and have obvious heating. In that case unplug the winding from the module.
