G'day,
I had a friend weld some tabs on my bike's frame today and I believe that I've damaged something and I'm looking for some advice.
Before welding anything I disconnected the ground connections, removed the coil from its mounts, disconnected the rec/reg and pulled the fuses from the panel believing that was adequate to protect the electrics. Unfortunately I didn't consider having the welders earth close to the job and we left it on the horizontal brace under the seat while welding at the front down tubes and a couple of tabs on the sub frame.
I'm running a capacitor with a Pamco unit and high output coil, HHB PMA and custom wiring. Bike was running fine before today, did 100miles just the other day.
So after reassembling the bike it wouldn't kick over and something strange I noticed was when I replaced the fuses and earths the headlight came on for a moment which indicates that the cap had some charge in it but of course it quickly drained. I pulled the plugs hooked them back up to the leads and earthed them to the frame and kicked but saw no spark.
I checked the fuse panel and all were intact except I am pretty sure that the headlight fuse was blown so I replaced it.
I then hooked a 12v battery up to the ignition and retested and had spark so I re-installed the plugs and the bike kicked over. I didn't let it run more than 5s and didn't rev it at all but it idled.
I pulled the pamco side cover off and had a quick visual inspection of the board and could see no signs of damage/burning but didn't pull the rotor off.
Given that after welding the bike ran with a separate power source and the cap was able to power the lights this is leading me to think that I've done something to the PMA but not sure what to do from here. At a guess if it is safe to do so I would think that I could leave it powered off the battery and kick it over and go buy a multimeter and read the PMA output either side of the rec/reg and cap but not too keen to race ahead without some educated advice.
Thanks for any help.
