Best regulator rectifier

[Steve]

I was not sure which other one to buy that would work on my bike for sure.

Apparently you missed post #19.

I am sure I will be happy with the unit either way. I am not worried. I am just glad it is here and I can install today.

Is there a location in which I can find installation directions for the compufire? I did buy the parts and am trying to find installation guide on the resources but no luck.

Thanks

no installation guide (for any of these aftermarket R/Rs) this is really good though - http://www.thegsresources.com/_forum...d.php?t=161397

short story install - replace the OEM R/R wire-for-wire (there are other wiring options but this one is the simplest)

black to ground
red to positive
the other three to the three coming out of the stator (in any order)

Looks like the g/w wire loops back to the r/w wire. Do I just cut this out? Also Do I need to replace old wire going to stator with new heavier gauge wire? Or do I just use the old wire and add the new pins? I created another thread thinking it would be good to separate the subject for future users to search compufire install.

Also the red wire looks like it goes to the fuse box. Does this get removed since the rr has a 40 amp fuse on the positive side?

It is my understanding that Electrex was recommended back then because Electrex was a sponsor of GSR.
I could be mistaken (again).

You are not mistaken!

I had to replace the starter clutch (dead when I bought the bike), so I, even though mine was charging OK, installed the Electrex at that time('96?).

I can't find a sh775 , on back order .

Standard practice is to eliminate that "mystery loop" and connect the wht/grn wire from the stator directly to the wht/red wire on the R/R. Since you are installing a new R/R that probably does not have a wht/red wire, just connect the three stator wires to the three inputs on the R/R.

There is no need to replace anything with heavier wire.

Also the red wire looks like it goes to the fuse box. Does this get removed since the rr has a 40 amp fuse on the positive side?

That would depend on how you connect your new R/R. If you connect the red output wire of the R/R to the stock red wire, you can eliminate the 40 amp fuse. However, if you connect your new R/R directly to the battery, you will need a 20 or 25 amp fuse in the line (not a 40) between the R/R and the battery. You will also need to make sure you fully insulate the stock red wire that is now dangling, as it will be 'hot' all the time. you don't want it touching anything.

You will also need to change the MAIN fuse in the fuse box to something larger than 15 amps. 20 amps might be OK, 25 will work for sure. This is because of the R/R being connected directly to the battery. Now, all of the current necessary to run the bike will be going through the main fuse ALL the time, not just before the engine starts. In the stock configuration, the battery provides power (through the MAIN fuse) until the engine starts, then the R/R provides power (through that dangling red wire). When the engine is turning fast enough to make more electricity than the bike needs, the excess is sent back through the MAIN fuse, in the other direction, to charge the battery. Because the load is split between the bike and charging the battery, the fuse never has to handle more than 15 amps. When you move the R/R wire to the battery, EVERYTHING has to go through the fuse ALL the time.
