    Hi,
    Could you please tell me what R4 is, is it 20ohm or 200ohm and would you have any idea why it keeps blowing?

    Thanks,

    Duke

    Good evening everybody,

    Helpful this post indeed!!! I have a major situation here, R4 resistor blow up like a nuke :) and put a hole in the RL1 Relay(Finder 21Vdc). Yes you're right, looks like C9 its long gone.
    Please help with some informations:
    1. I understand R4 is 20 but 10W or 25W ?(on the math paper schematic its 25W and on picture schematic is 10W).
    2. About Finder RL1 Relay, coil at 21Vdc is hard to get(delivery time 4 weeks and minimum 10pcs). Do you suggest an replacement 24Vdc or some other brands ?(Omron, Panasonic do not carry 21Vdc coil voltage).

    All the best
    David

    That's exactly what happened to mine, my RL1 still seems to work though with a hole melted in the case. Let me know if you find a replacement.
