Hello all,
I'm a newbie member with perhaps an unusual problem and very basic circuit knowledge. I am attempting to repair a voltage regulator for my Russian motorcycle which uses a generator rather than an alternator. The system itself is 12 volt and like a car is designed to be regulated around 14.5 volts. The regulator consists of a circuit board with various components soldered to it and enclosed in a simple metal case. I found one diode which visually seems bad (it has a burn mark on the side) and using an ohm meter it measures the same resistance in both directions. Printed on the diode is:
78R7
GBX
W1
My first question is do these mean anything to anyone, or does anyone know of a US-Russian cross reference (as ridiculous as that may sound). Secondly, does anyone know of a Russian Electronic spec sheet or some way I can figure out some specs for these components?
Buying spare parts for this bike is a bit of a hassle and is why I'm trying to fix this one. Thanks in advance!
