Batteryless wiring

I think the polarity of the DC output from the Tympanium unit will determine positve or negative earth.

Unless you plan on running other electrical components that require a negative ground system (electronic tach, etc..), positive ground works just fine.

Englishman has posted wiring diagrams on THBC, & some of the Brit parts dealers web sites also have these posted.

Go with positive ground.

Look in the manual for the TT wiring diagram. It was a batteryl ess system just like your thinking about using. Since your using an electronic regulator, ignore the part about the stock regulating system. Keep the system Positive Ground as that how everything is designed to be. The stock system used two capacitors and you should too.

The TT Triumphs used the ET system (they called it energy transfer). This used a 5-wire alternator that had to be "phased" correctly w/ a model specific rotor. They also had a different degree AA unit. This system can become Excedrin headache #9. Don't go there.

Opps! Didn't know that. I thought they used the three wire unit. Since his charging system is already set (alt/reg/bat) shouldn't he be able to use the diagram to wire the lights, ignition switch, coils, brake lite switch and to locate the capicators in the right spot?

Thanks Englishman, Are the coils wired differently also then?

+ on the coil would still be positive, even if you are going negative ground.
So yeah, just flip them around.

hey englishman, would you need to sub a capacitor in place of the battery if you're not going to use it? i've been looking at diagrams today and i keep seeing that popping up there. i'm also figuring out how to re-wire my trump.

Hey Tony, what other diagrams were you lookin at?

the one in the M.A.P. Cycle catalogue. and what i have in a restoration/troubleshooting book on 500/650/750's.

mity max has a capacitor, so no
tympanium does not, so yes

I'm not running a mity max, but I got a big capacitor, will that still work? Or should I just put a battery in it? I talked to Hatch and I swear this is the way he was doin it.

I do em all the same on my triumphs....points, harley coil, tympanium, capacitor, positive ground, no battery. I'm no electrician, so I havent tried the negative ground switchover yet, but I heard it's no problem.

Whats the difference from the stock coils, and the Harley coil? Will any Harley coil work with this setup?

Hey Hatch, I'll probably be seeing you this weekend if you'll be around. Maybe we could hang out for a bit, or grab a beer.

Are you guys setting up at the junkfest?....I'll be there on saturday. I hope you meant HANG out.....PLEASE tell me that's a typo LOL!!!!

Wooow !! Yeah, that was a typo, I better stop drinkin now.

i can unnerstand typing a "m" when you meant "n"; or "p" when you meant "o", or something like that. but how do you confuse a "w" for an "h"???

i think that this was a freudian slip and not a typo.
