started working on the wiring by checking the voltages going to the board and the monitor. unfortunately, i forgot that the wiring harness i'm using is
NOT from the original cab, but from the usa - which means american voltages
.
here's the line filter assembly just behind the power cord
because of my forgetfulness, i didn't use a step-down converter and when i plugged in the power plug, i heard a very loud bang and smoke was coming out of the line filter assembly: the metal oxide varistor (MOV) was blown!
the MOV is labeled as V150LA10A
i checked the schematics and found the following
obviously the V150LA10A varistor is used for a 120V line, but you can also use a varistor labeled V275LA15A for a 240V line!
questions:
- can i simply replace the blown varistor with the V275LA15A variant and then use the wiring harness without a 240V > 120V stepdown converter?
- i need to order replacements and of course rs online comes to my mind (free shipping). however, they do not carry the exact model so i was wondering whether
any of these would work (differents amps and stuff). i have no experience with varistors, therefore i'd better ask ...
- is it possible that the line filter was blown as well or is the varistor there to protect it?
looking forward to your input, guys!
