i have a 82 model with the "5V4" TCI box and up until last night and now again it has yet to send a spark to the plugs.a motorcycle mechanic friend came over last night and checked this and that with a meter and determined that the cause of the lack of fire was the TCI- the coil and pickup coil both tested good with current to the ignition coil.
after we finally got the box off the battery box he checked the connertors with a meter and wiggled this and that and low and behold we plugged the box back in and there was spark at the plugs. he said the white wire with red trace was suspect and probably needed re soldering, which we redid today at the shop- now no fire again!
i replaced the 4 diodes in D1 thru 4 thinking that might be it. still no fire.
any thoughts? i sure hate to ebay another box.
they had a TID 12 box at the shop but the wiring termils is different- the 12 box only has 5 wires and the 5V4 has 7.
and input appreciated.
