I removed the ACRY unit and examined it. According to the service manual, there should be 120VAC at the transformer connection, but I am only measuring 47VAC. So, I started looking at individual components (which are practically impossible to find today, though I did just find yesterday a 25 pack of the KC103P capacitors on eBay). The capacitors appeared to test ok. The relay, when i plug the board into the wall, did not click, however I did desolder it and manually connected it to my motorcycle battery and it at least did click then (Ive ordered a replacement that matches the pin layout and the specs, minus the TV rating). I desoldered the diode and it tested ok.
I then desoldered the induction coil (L50 on the board) and it tests at or around zero, which indicates it is bad. So, my question is how do I determine what an adequate replacement part would be for it? There are no specs marked on it, only what appears to be a part number which turns up zilch in a google search. The service manual does not list this part for the ACRY unit, but it DOES list a filter (denoted as F50 in the manual, despite the fact there is NO F50 on the board), so I was thinking maybe this was a typo because an induction coil can be considered a filter. so, the service manual lists this "filter" as part number DTF1012.
At pacparts they have a listing for that part, and the order page for it says it is not in stock, but is available for order. I ordered the part yesterday morning, but today was issued a refund because **surprise!!** the part isn't ACTUALLY available.
So, I'm stuck and at a loss. Do any of you have any suggestions?
