that is the load resistor on the regulator,they rarely go open circuit-only if the regulator is short circuit and the chassis is left powered on for a long time
it should be 200 ohm,read it with a meter
you need to check the hot and regulator(both mounted at opposite heat shields) but almost certainly TH2 will be open circuit one side(should read about 1 ohm one side and around 60 ohms the other)
the black wire hanging down is the dag earth from the tube and should plug into a spade header on the neck card,it has obviously broken off which is quite common-you can hard wire back in,its marked FS9 on the neck card
Hi,
So I tested this out. The load resistor on the regulator is reading 6.00k ohms with the multimeter leads one way and 0.666k ohms the other way round. The slot in the resistor looks like it has something in it that looks a lot like sand. Is that normal? I'll put a pic here so you can see it (resistor.jpg).
I checked the HOT, which reads around 39.4k on both sides (c to e and c to b).
The regulator reads around 156k ohms on both sides (c to e and c to b).
What's the correct way to read TH2? I can see four terminals on the top, two with really fine wire going to them from what I can see and two with a thicker wire.
I also noticed while having a look at the board, that two of the pins on the flyback haven't been soldered to the board. Is that normal too? I have attached a pic of that in 'flyback_pins.jpg', where you can see the pins towards the bottom.
I noticed the biggest cap is bulging at the top so I'll be replacing all the caps I think, once I find out what's wrong here. I've seen cap kits on Ian Kelloggs site, with the HOT too, but I can't seem to see the regulator anywhere. TIPL751 is the part number if anyone knows where to find one.
Thanks guys, hopefully this can all be repaired!
