Honda Spree and Elite 50 Forums

Hello all, I just picked up a 86 spree and I got it with no battery and tin foil around the blown fuse. I got a battery and put in a new fuse and it blew right away. Even with the key off it will blow. Here is what I have done. I read through the repair manual PDF and the stator is reading good. Now do I check the recifier/regulator? also when I disconnect the regulator it doesnt blow the fuse (doesnt surprise me seeing that it kills pretty much all power) And if I disconnect the white wire going to the stator the fuse will hold.

So to sum it up.
-Blows fuse even with the key off if the battery is hooked up
-with no battery everything works when running and doesnt blow fuse
-doesnt blow fuse with battery in and white wire unhooked from the stator

Let me know if you need any other info. Thanks for the help

Why are you asking us anything? You already troubleshot this and determined what is wrong. Just replace it. FYI, electrically the stator never sees the battery if everything is working properly.

So you think its the regulator?

The stator is giving me the correct ohms on all three wires. Is there a way to check the regulator?

Test procedure is in the manual. You need an ohmmeter to preform it. But you already tested it. Plugged in the regulator/rectifier blows the fuse. No regulator/rectifier fuse does not blow. If the rectifier is working properly, the battery does not electrically see the stator, besides the stator checks good, so replace the regulator/rectifier.

But when I plug the rectifier in and unplug the white wire going to the stator the fuse doesnt blow. But I will pickup a rectifier and try it anyway.

Yes - good testing and confirmation of a bad regulator.

It should not be allowing current flow back into the (AC) outputs of the stator.

AAHHHH! Recifier aka series of diods! If its letting the voltage to back through the windings of the stator to ground that would easily blow that fuse!!! Excelent! Sometimes i get thinking to far into things! thanks guys! just ordered one and I will let you know the outcome by next week.

I have a Honda Aero 50 with a blown fuse. I also have a Honda Elite 50 parts moped, I pulled the fuse from it.

The Aero 50 fuse is a 7 AMP and the Elite fuse is a 10 AMP. Would it be ok to use the 10 AMP in the Aero?

I tried it just to test and make sure the fuse was the only problem and everything worked ok with the 10 AMP. I just didn't want to leave it in if it could make everything explode under my butt explode or something horrendous.

having a few amps higher fuse would make your wires get hotter in the event of an electrical problem before the fuse burns out. 3 amp difference shouldnt matter much but lets say you put a 30 amp fuse in there, your wires could melt together before the fuse gets hot enough to melt in two

It is no no ! You are overload the wiring circuit.

When did fuses start determining how much current a circuit draws? Try NEVER! The ten amp will work but it would be a good idea to get the original 7 because if you get a short, then is when the problems start. For normal operating conditions, you will never know the difference.
