1980 750H bare bones for mattylight

Hi, again, seems I do have one more question about the starter switch in the diagram. Normally the first position is off, second is power on and 3rd is momentary for the starter. Is it just an on off switch in your diagram or do I need a 3 position switch? Thanks again.

The starter button on KZ's is just a simple momentary push-button. The ignition switch in my diagram is a simple on-off toggle switch.

You could adapt a car-type ignition switch with momentary start-position if you want. I could show that in the diagram if that's the type of switch you plan to buy.

Thanks, I think I will use it as in your diagram. I sure wish you lived close to here.

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!

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!
