I have found someone who can repair the 1992-94 81980-24020 Flasher units. He is Josh at relentlessmotorsportsllc.com . He quoted me
$35 to repair mine, but it ended up costing $45 because he had to replace more parts than he expected. Cheap for something that is
unobtainium! He has a 1992 SC300 and tested mine in his car before he sent it back. Works fine in my car now. I sent him my spare for
repairs last week. He said that he found acid on the board, caught it just in time, and cleaned it up, which possibly indicated a leaking
capacitor. The contacts on the coils also may be going bad. Relentless Motorsports also repairs ECU units. He uses Japanese parts
as much as possible. Two thumbs up!

Thank you for this heads up Fred!!!!

I'm going to add a link to this thread with your main post quoted in the 92-94 SC flasher unit diagnosis thread.

As we discussed over the phone, if the capacitors and contacts on the coils represent the most common failure points then you may just have given the majority of 92-94 SC owners with this flasher relay issue a good workable fix. It seems to have worked out well for you!

I will still be sending one of my space 81980-24020 flasher relay units to CL member Lexus2000 soon so that he can attempt to analyze the workings of the relay and see where that also leads us.

However as with ECU repairs this may ultimately be the fix that works for most 1992-1994 owners!!!
