regulator/rectifier

Post by 1oilcan2 »



is there any difference in the regulator/rectifier from a 1985 1200 Ltd and a 1986 1200 Se other than the 85 utilizes 2 plugs for the wiring where as the 86 uses only one plug for the same wiring. could a reg./rec. from a 86 se be used on an 85 Ltd or did the Ltd model use a different one therefore the reason to use 2 plugs for the wiring the reason I ask is the reg./rec./ on my 85 Ltd has failed I can get a used one from a 86 Se the only difference that I can see is the part # and the fact that the 86 has all wires in one 1 plug where as the 85 has 2 plugs the single plug on the 86 is the same as the big plug on the 85 which has 2 empty slots for wires but those 2 wires are in a separate plug. I realize I will have to use the plug assembly from the 85 which will require the terminals to be changed from the plug assembly

Any three-phase rec/reg from any make/model bike are pretty much the same and will work. Major differences will be physical mounting and connector plugs, but otherwise they all do the same thing and will be electrically compatible, barring wattage capacity.

Go ahead and use the '86 rec/reg. You could actually adapt one from a Yamaha if you wanted to.... :lol:

The RR from the '86 SEi, I believe that is what you are mentioning, will work on the '85 Limited Edition. As you mention, remove the wires from the SEi plug and put the wires back into the 2 plugs the '85 uses.

It is mentioned that any 3 phase RR will work and this is true; however, the stator is a 500 watt on the '85 Limited Edition and '86 SEi. The amp rating for the RR should be at least 35 amps. The other 1200 RRs are for 350 watt stators that only require a 28/29 amp rated RR. This is what you have to be aware of. I had a second '85 Limited Edition (have since sold it) and the PO had used an RR from a 750 Yamaha. It worked even though it was rated at a lower amperage rating than that required, but I'm a fan of the external alt mod (Poorboy) so the RR came off and I installed the external alt mod.

I had an RR from an '84 1200 Aspencade that I gifted to a fellow in Vancouver BC for his 1000 V-Strom. He hooked it up and it is working well.

There are also off shore copies of the Compufire 55402 series RR, or find a used one and install. The off shore ones are inexpensive and worth a look. To caveat this statement, you can have good/bad experiences with apparently made in the USA, or OEM products. No guarantees when it comes to electronics.

Good luck

Thanks for the replies I got the one from the 86 Sei and rewired it works great I had to use a couple male /female ends for 2 of the wires from the stator as the one plug was pretty much melted. I am seriously thinking of doing away with all the connectors and hard wire it I recall a few members mentioning that on the forum. the po had already hard wired the connector by the battery where the wires come out from the engine I think that may be the way to go short of getting new replacement plugs and inserts. as mentioned thanks again for the help :D

Good to hear all is well with the SEi RR. The main issue as I think is that the connectors in the RR system fail due to corrosion, dirt, and other forms of crud. Clean connectors will mitigate this and allow for normal maintenance/work, and disconnecting if necessary. This has been mentioned on other threads as well. Poor electrical performance has been rectified by removing and cleaning the various connectors, lots of crud builds up over the years and not just in the RR system. Poor grounds are another issue, doesn't help any system.

Cheers
