I'm putting this tip here, I hope is a good hint on start problems with the 1500's, I was going to put it in the Tech Forum, but it moves so fast that some experienciong the problems I had, might miss it...Trust me, Jerryk, 93Wing and myself worked on this "No Start" problem for hours before we finally found the cause and fixed it...

Right at this point 93Wing and myself are trying to get the 94 1500 I got from Jerryk up and running...One of the major problems was it had a wiring short, the PO before Jerryk had "Rigged In: a push start button from the local parts house...It worked but the button on the handle bars was dead...Jerry and I were able to start it by crossing the terminals on the solenoid, but couldn't find where this one wire went...

93Wing brought his meter over and for over three hours we checked and traced, then finally cut the wiring harness open in a couple of places trying to find this one tiny brown wire with silver rings on it...Couldn't find diode "A" or "B"...??? finally we found that wire after taking off the right saddle bag and tour box to where we could see....In the picture below areseven breakers and this one diode "bank"....Took it off and sure enough two diodes were bad, one was shorted out...I looked at just buying that one piece, lowest price I found new was like $65.00 to over $100.00.....This diode controller has eleven wires going into it, so it controls several items, I believe reverse too...

I found the following items at Pinwall Cycles for $9.95 plus shipping...Charles took it and checked it out again, it was good, plugged it in hooked up the battery and if cranked over at the handle bar switch.....Like I said I'm not exactly sure what all it controls but with eleven wires going to the diodes in it, my guess is that it might be the answer to some start, reverse problems...If I'm wrong then I've wasted a lot of time, but it did solve our problem...

The one I'm taking about would be the one on the lower right.....Now the carbs are offto see if we can find out where its flooding from and repair, or rebuild as necessary...My hat is off to Charles aka 93Wing for all of his help in getting that Wing to this point...

The diode assembly you are talking about is called "the reverse diode assembly" it does provide the ground path for the starting and the reverse functions of the bike.

Thank You Terry I just couldn't think of the name of it this morning...You are totally right.....I do know this for a fact if it has "blown diodes" it can cause you to start pulling hair...It did take us a long time to find that little sucker and I wish you could have been standing there when we turned the key on and cranked it over with the "factory" start button...Yeah it was a thrill.....!!!!!!

You can also make up a diode pack with some silicon power diodes. Just cut the connector end off the diode pack and solder in the necessary diodes. Connect them according to the wiring diagram in the service manual's schematic. I made up a pack for a bike I had in my shop when they guy needed it in a hurry. I molded some epoxy around them to package and protect the diodes. Worked just fine and the necessary diodes are cheap at Radio Shack.

When I hit the start button Claude had a grin from ear to ear, that made him a happy camper.





The manual is pretty clear as to how they are arranged and how they are connected together. Rest assured if this happens, to me or to someone else I am helping I will be making a diode assembly and encasing it in silicone or epoxy.

It's always a thrill to repair something that has fought you or so illusive, electrical problems can be a nightmare. The best solution for these is the factory service manual with the electrical troubleshooting section, it has saved me countless hours of chasing problems.

And don't forget on the 1500 to check the reverse lever is fully home........



Guess how many bits I'd pulled off before someone suggested I check ! :wtf:
