Hmm... interesting. That symptom sounds like the "12 volt "hot" source MUST be 12 volt or else you'll see overly high regulator output" warning they mention in the instructions. Hopefully that's all it is for you and cleaning things up will sort it out. 57k is still a pretty good run...

Oh, and I see you're in Georgia - it gets even hotter there than it does here. Maybe that will help me out, too... I like riding in the cold, anyhow.

and believe me, it was a rough 57k FWIW, the bike still runs and charges fine

If you look at every factory bike, the OEM's all mount the regulator up front where the horn would normaly be on an Airhead. On my R80 ST, I had mine mounted under the seat in the battery compartment. My unit fried, but I think it was a connector failure, not excessive heat that did it. Anyway I mounted my second unit up front, directly on the front engine cover. I don't recommend this either because the front cover gets hot when you park. So I still have the regulator bolted to the front cover, but I have insulated the regulator from the cover. That seems to work well. It never gets warm.

The horn bracket looks like a good spot. My horn's not very dirty so I think it'd be safe to put it there, tucked up behind the fender. That'd be about the shortest distance between alternator & VR as you can get.

I mounted mine on an aluminum plate between my rear fender and the battery. I don't have side covers so there's plenty of air flow. No probs at all.

I'd love to be able to mount my regulator near the battery. On the GSPD, there is no place for it. The battery is mounted sideways which eats up all the space from the airbox to the fender. On one side you have the exhaust running not too far away, as well as a small fuse box. On the other side are the battery terminals and the shock isn't too far away which also interferes a bit (I thought about mounting it against the battery on that side but I'm afraid of the shock crashing into the regulator if I did, plus it's still not a great spot with the battery cables running right next to it, and there isn't a great place to even attach it to at that point.

I removed the old system in about 90 minutes today. I'll probably decide tomorrow where to mount it when I install the new stuff (though I don't expect to finish it tomorrow).

I consider good cooling to be more important than close to the battery, but due to impedance considerations closer to the alternator is possibly something of importance.
Both these are covered by mounting forward.

There are reasons why all automotive alt.s work like the our stock boxer setup. Permanent magnet setups are making full power all the time. That takes power wasted that could be turning your back wheel AND there is a lot of wasted energy to get rid of via that heat sink of a regulator. I would keep in front and in moving air.

Man! I don't have any issues with the stock setup but I haven't turned my bike into a artificial daylight and do-dad machine either! :)

You're in San Francisco - you don't suffer the winters I do.

The stock system simply won't run a heated vest and the heated grips at the same time (I end up with really mild heat from both if I try). Previously I've just run the vest and shoved single-use heat packs in my gloves but that doesn't work as well as the grips for keeping my fingers from going numb. This also doesn't help when an unexpected cold rain starts to fall. Personally, I like the simplicity of the stock system but it just doesn't do what I need. It was either this, or buy a new R12GSA, and this is a good amount cheaper.

Just putting the bike back together after a tranny rebuild - think I had the ground wire routed differently before.

Try that without an Odyssey battery. That is the area I looked in for mounting it, but with a full-sized battery in place it runs a bit too close to the shock...

And you don't suffer the summers that I do!

I have my bike on high beam all day everyday I ride and I use an electric vest all the time. Heated grips? I don't care for them. Plus I know better than to run too much stuff.

The wiring in some of these photos speaks volumes to me!

A lot of people worry too much!

So long as the FINS are in the breeze, it'll be OK... and the installation doesn't look like a dogs dinner A little bit of juggling helps.
