How do I test the TCI and Coil? Just probe the proper wires with the ignition on? Stupid question I know but just want to do it properlyThinking aloud, always the possibility of an error in the harness, check that both coil and TCI have plus 12 supplied.A test light is best for that as it shows both voltage and enough current to actually do the job. I'm a fan of "a turn signal bulb". with some leads and clips.
Awesome. I will definitely be trying that later. Thank you!Quick and dirty coil test (any coil)....
Make sure you have 12v at the red wire (power in).
Remove spark plugs and plug 'em back into the coil... make sure they're grounded to the engine.
Take the orange wire... the one attached to the coil and tap it to the frame.... tap tap tap... every time you tap it the plugs should give a nice fat blue spark.
Explanation..... every time you ground the coil (tap), it charges. When you lift the wire off the frame (un-tap?) the secondary discharges.... blue sparks ensue.
Remember that for a "stuck on the side of the road" test.
How much do you want for it??I've got a TCI box I can part with, came off my '80 Special a couple months back when I switched over to Pamco... Far as I know nothing wrong with it, only reason I bothered to change it is cuz I got the Pamco kicked down for free from a friend...
Haha! No worries!! That's cool!Ha! You keep gett'in stuck with me, as everyone else on this site is asleep and I often quit tinker'in on scoots about now (carbs work and new VAPE ignition on my '74 RD tonight).
Aside from throttle butterflies in the wrong position, an electrical issue may be tricking the ignition to advance early. Other possibility is an air leak @ intake manifold. Carb synch can sometimes cause that too.
I did notice in the pic of your bike that the large ground eyelet normally attached to top motor mount is unhooked. Perhaps the motor is not well grounded and screwing the e-advance in TCI box. Excess rpm may have produced excess voltage on charge circuit, popping a fuse. I'm mostly guessing here as I can't remember having this issue myself.
Not quite. My switch is from TC Bros and it's got Batt, Ground, Acc, Ignition and Starter terminals.I reckon the switch diagram that I drew-up last night matches the type of switch you're using?
Tbh I'm really not sure... What's a fair price?How much do you want for it??
Not sure man, that's up to you! LolTbh I'm really not sure... What's a fair price?
