Electrical help needed

Hello all, new to the form and new to choppers, I have recently acquired an all custom chopper that is giving me some electrical Gremlins. Everything starts out fine, then when I drive it and it gets too warm up temp if I shut the bike down, I lose electrical ignition, including all the lights. It has a pro 1 ignition set up on it. The wierd part is when this happens, if I try to bump start it, it's obviously not enough to start the bike but the lights come back on and Im able to start it via the switch. I am at a loss here.

Welcome.
If every circuit is down or on/ off- the problem is at least at the level of either main fuse, or ignition switch or battery cables. Poor connection? Poor ground?
If only ignition acts out when the engine is hot- it could be the module is about to go south.
If runs for a while and dies or can,t be fired up ( not enough juice) - battery and charging system should be tested.

Thanks for the reply, the battery is brand new, and it's the entire system that acts up lights and ignition. I will get a picture up to help better describe when I get access to a computer.

Check to see if you have a self resetting circuit breaker...with the lights involved too , it really sounds like the culprit....just run a jumper across it and see if it stops acting up..

OK, here is the PIC, when everything is fine the green light illuminates when in neutral and the head/tail lights come on, when I go out for a ride and come back turn off key then turn back on I have no head/tail lights, no ignition and no green light.

If you check the pic in my post above, I have taken apart the housing with the green light and it does look like there are 4 self resetting breakers in there. I agree that this sounds like it could be the prob, let me investigate.

that phat man diggin it ......... check all contacts are clean and tight ... butchya done that already, those reset breakers never liked em ... I replaced all mine with correct fuses as the breakers can reset before you get covers off there by hiding the issue, fuse blown .... find out why replace ..... just my $worth .good fortune on the road man :-)

Ok all, I am stumped...the bike started up last week, so I took it for a spin...about 20 min out on the way home...it died mid cruise...seemed to me like it lost spark, ignition....everything was dead. I towed it home and today started to dig in. took the battery to have it tested...its good but needed charged so theres probably a draw somewhere. I have checked the 4 self resetting circuit breakers and all are good. there is a relay that comes off the main line and I assume it goes down to the starter and that was replaced..... This is what I don't understand. My initial thought is the ignition switch is bad... Im checking continuity through the ignition lines (there are 3) it has three positions....off....start....and start with lights. So one ignition line has continuity on both the neg and pos terminals. the other two lines have continuity on just the neg terminals. Also the coils have continuity on just the neg terminal only. Am I totally off base here. I thought these would only be through the positive side of the battery. Everything is pretty much hooked up like its ready to go yet I still have nothing. I have yet to check down on/near the starter cause it looks like a bitch to get to. any thoughts

Can you simplify the ignition switch tests by placing a jumper across the terminals? if you jumper the switch from the battery.... in.... terminal across to the hot.... out..... of the switch.... do you get any thing? you should have coils, module etc....also try this to the lights terminal...any lights?

I jumped it...and nothing, when I hook the neg terminal of tester to neg of battery and pos to ignition (in) it reads 12 volts.....when I turn the key on in either position I get 0 volts at any connection at the ignition switch....does this mean the switch is bad?

Just to clarify, I only jumped the wires between the ignition switch itself.....I just now went out and jumped directly from the battery positive terminal to the ignition out switch and I have lights and ignition, but it dies as soon as the jump is disconnected.

Your first test is saying that your switch is bad......your second test sounds like you have a loose connection in the wire from the battery to the switch..since you read 12 volts with a test meter,but it wont handle a load..maybe a dirty connection..or dirty...burnt... inside the switch..

I just replaced the switch on my bike, it was doing the same thing....when mine lost connection and came back on, it sounded like a hand grenade
I was scared I was going to blow the pipes off..

Ok...messing around with it today...and I hooked everything up like it was.....got it started and the positive terminal/cable got waaayyyyy hot.....like burn your finger hot. Turned it off and just like before....nothing now.

Edited to add... When I got the bike, the headlight was acting up...I checked into it and the plug looked as if it had gotten hot and melted some....so I replaced the plug...headlight was/is now working fine....however Up near the electrics (circuit breakers and what not) is a high beam switch.....I disconnected this switch for shits and giggles...and the bike will run....no issues....as soon as I connect power to the switch/lights...it kills everything, ignition, lights, all power.... So im thinking there's a short somewhere in That system....possibly tripping the main circuit breaker.....
