Need new regulator/rectifier unit

[RED1978]

Hi Guys my reg/rect unit failed the test described in the manual and my tach doesn't work and the charging thing isn't happening so I'm in the market for regulators. Thought read somwhere someone had some updated improved ones? Can't find it again, though.

member Geezer out in the PNW find Oregon Motorcycle Parts and has a better reg/rec unit.

The Geezer unit is excellent. I bought one. Well worth the money and it gives full charging at much lower revs. A great piece of kit!

If you're interested in a DIY setup with off the shelf parts, I can look up some links I used for my setup and what I changed.

I'm using a generic off the shelf regulator for a car and 2 bridge rectifiers. I've been running it for a while now with no problems (and no dead battery!).

If you want to keep it closest to stock and easy plug and play, geezer is definitely the way to go. I went with my setup for two reasons: 1. Maintainability - easy to find parts when on the road 2. To gain a better understanding of how all this works instead of a black box solution.

I would love to see it!

Agree

Posting a DIY guide here may help someone on the road who needs an emergency fix with no OEM part source.

I will locate the original links I found previously and post exactly what parts I used and how I wired it up. I ended up buying a small aluminum enclosure and thermal epoxy for the rectifiers that I put behind the battery box and was able to fit the regulator under the tank.

I did this on my XJ with some help from crazy steve in this thread:

It has been about 3 months with no problems. I have yet to mount a voltmeter, but every time I've checked voltage at idle and revved, I haven't seen any problems.

I also wired up all of the rectifiers thanks to some assistance from a friend who pointed out how to get the most out of the radio shack bridge rectifiers.

The forum where I found the original information has two different scenarios, one for the XJ650 charging system and the other for the earlier '78 XS650, which should translate to the XS11 charging system. I plan on doing this for my XS as well once I get to that point in my rebuild.

I should be able to get all of the info together tomorrow evening.
