1987 Honda TRX125 cdi wiring trouble/no spark August 04, 2014, 08:55:26 pm Buddy of mine went by the scrap yard and saw an ATV on top of the heap. He crawled up there and saw "HONDA" on the side cover. Told the guy he'd give him $100 for it. The owner agreed on $140. He wants a bomb around quad for guests to be able to ride, as little initial investment as humanly possible the better. He took it home and the CDI box was hanging by one plug. The other had been ripped off at some point and someone had replaced the pins with crimp on connectors which were now all confused and mixed up. I have found some replacement harnesses on Ebay but apparently Honda changed the harness plugs and things like every year during production.
