Honda Spree and Elite 50 Forums

Hi, I have an 85-87 Spree wire harness. This is the connector from the back, orientation of the CDI is if you stood it up on end (like a skyscraper) with the connector on the bottom Black/Red Black/White Green Black/Yellow No connect Blue/Yellow (tab) 2nd color is the stripe

First - remove the 2 bolts holding the plastic fan and remove the fan. Take off the nut in the center of the flywheel. There are at least 2 options for pulling the flywheel: 1) Buy a specifc puller for your flywheel. That's what the Spree manual shows. It screws into an internal thread just outside ...

The kill switch only kills the ignition. Starter will run just as you describe. No spark - Lot of parts involoved, narrow it down a bit... Check out the Spree service manual in the tech section of this site. Run the resistance checks over everything - Exciter coil, pulser coil, ign coil Check out th...

My intent for the bystarter test was for you to unhook the wire before starting so it would never *close*. When open it lets in more air but also richens the mixture. When you verified that the bystarter was closed, right after your engine was running poorly - that's the same diagnosis with a differ...

It does sound like your bystarter is working ok from your past posts. Could it be possible that when the bystarter closes, your scooter is running too lean? One easy thing to do is to try unplugging one of the bystarter wire to keep it in the enrichen mode. If works better, re-check the idle jet (I ...

Hi, Beyond the resistance checks in the manual, there's not much info (in the manual) for in-circuit testing. Is it feasible to swap in a known good one or try yours in another scooter? As stated in the manual, weak spark can be CDI, Ignition coil, Alternator exciter coil, Pulse generator and igniti...

Voltage measurements sound ok, you are charging at idle, the headlight circuit works with a typical dim bulb at idle (7.7v). Input to reg is probably ok seing that you have 14.5v output. Yeah - I have no tach either, pretty much set by ear, faster than sounding like it will die, but below trying to ...

The 85 Aero manual in the Technical docs section says 4th notch from the top.

I took a Fluke 8012 DMM to an '87 Aero regulator, and got some weird readings. They didn't match the manual. I need to verify the regulator is working before I post anything. In circuit voltage measurements are a better guide to functionality in my opinion, because they show the 'man on the inside' ...

Its a low cost way to make the headlights/instrument lights and whatever else like the bystarter only be powered when the engine is running. It saves a relay or electronic switch. Efficiency wise its good too, it avoids regulation losses.

Trace the melted wires on your wiring diagram. If one of the melted green wires is the one between the regulator and ground, then yes, it would be an indication that something abnormal was going on with the rectifier/regulator assembly. Something that may or may not caused damage to the regulator. I...

A member recently got a plume of smoke and some think his regulator is now bad, after installing the battery backwards. Don't know if that's similar to the cause of your melted green wires. The 7amp fuse should be protecting against melting from most electrical problems. Could someone have subustitu...

Check the voltage on your headlight too. It looks from the schematic that the tap driving the lights and bystarter is directly on the alternator, which would mean it's not DC. Try setting your meter to AC if you find weird readings on your headlight too. For your license plate light - check both sid...

I think you mean 'auto bystater' here by the context.

It gets power from your headlight circuit. You will not find voltage across it with the key 'on' *unless* the engine is running.

The wiring diagram in the manual shows 7A also. If you trace the wiring, the starter current itself does not flow through the fuse. There's a fat red wire that goes from the battery to one starter relay contact, the other contact runs to the starter. There should not be current flowing that would ex...
