i have a stock electronic ignition, could i just use the diagram for the dyna s for reference? Its an 82 kz750 n1.

There are a few differences such as which coil is mounted on which side and the reg/rec is a single unit. some of the wire colors are different.

thanks this is awesome.

Wow, its been awhile since I've been on this thread and I'm amazed by how many responses there are now... loudhvx is the man!! I've been doing a lot on the bike recently and I finally finished enough to fire it up and first button push it worked great! Thanks for all your help!
Matt

Glad it worked!

I don't know where else to put these, so I'll put them here. They were probably in other threads originally, but chronologically, they would go about here if they were in this thread.

Another question for loudhvox. I am planning to hook up an external alternator. Can I run that along with the bike motor alternator? It is a one wire alternator. Almost finished with your great bare bones wiring diagram. Hope to start it soon. I think I need the extra charging as I am running an electrical reverse gear drive.
The engine is going in the large buggy and not the motorcycle so reverse is important. Thanks again for all your past help. I hope to have pictures soon to share with everyone.

The one wire alternator will have a built-in regulator/rectifier. Since the bike, now cart, has its own regulator, there will be two regulators fighting over control of the voltage. If the bike is using a lot of electricity it's not a problem, but when the bike has too much electricity, the bike regulator may fry.

You could maybe put in a switch so the KZ alternator/rectifier/regulator only comes on when the reverse is used. The single-wire (GM?) alternator should have more than enough power to power the cart during normal times.

You could also use a really big, (Or a bunch of small) diodes to reduce the voltage coming out of the GM alternator. This would make it provide current only under heavy load, such as when the reverse is used.

I'm sure there are other configurations that might work as well.

The main thing, though, is that you will need a much bigger battery, like a car battery. (I don't remember if you already said you are going to do that.) The alternators might only provide 20 amps or so at idle (which is probably what the engine will do when you're backing up). You need a big battery to give you the extra current.

I think the simplest solution, however, would be to just use a car battery and don't bother with the external alternator.

Better yet, but more work, would be to delete the KZ alternator/reg/rec and use only the external alternator. It would give you more electrical power (and is better suited to such extremely varying loads), but will require more fabrication. Some people put a pulley where the original alternator was and run a belt to the external alternator.

Again, as usual, you were a big help. Thank You.

Question for Loudhvx,

I'm after a diagram for my z650 fitted with gpz750 engine (and ignition system etc). I don't want any of the cut outs (clutch, side stand etc) and I don't want the indicators, but I'll need everything else (gauge lights, headlight & taillight) Being in the UK I won't need the headlight on all the time. Can you help at all?

I've printed off the ignition/charging system from the beginning of this thread, which was a great help, but I'll need all the rest - cos I ain't that clever!

Sorry, I don't really have time to go through all of the gauges etc. If you're keeping all of that, then a stock wiring diagram will be more useful anyway.

I don't know what year your gpz motor is, but here is a generic diagram to show ignition and charging to get it running, and a generic setup for some lights and basic idiot lights. All the rest of the gauge lights etc can be wired into the area to the right.

This is for Dulcimerbob.

You can probably go off this diagram I made for Cherrymetal's GPZ750. Your 84 GPZ550 should be very similar. Also, yes, you can just use individual spade connectors on the reg/rec. I often do. I like it because it's less bulky and I can hide the wiring better that way. But definitely get a good ratcheting crimper, otherwise you will waste your time.

Here's a decent one:

Can't seem to find this one for some reason.
I suggest using the one for Zeffrides. It is on page 19 of the Mattylight thread.

If I find the original drawing I'll post it here.

Hi to all. I finally got around to wiring the engine using the diagram from Loudhvox. It started the first time, again, thanks Loudhvox.
