Was having a start button problem on Popeye. Just want to start a new post. I have found that the 2nd ball optic switch isn't working. I looked at the transmitter side with my phone camera and all are lit. Tried jumping the leads on Q5 on receiver side in test and nothing, all others would trip the switch. I reflowed pins and inspected optic PCBs and all look good. Any advice? Getting flustered.
