Polaris Rectifier mounting help

[prichmon]

I purchased a R/R from a 800cc RZR. This thing is huge compared the stocker on my 78 gs550. Can someone point me to a good location to mount this fella?

Thanks

Do a search; this topic and a thread came up recently.

Just to be sure you got the right one, does it have "SH775 BA" on the back fin?

I was not aware that the "proper" R/R came on the 800cc unit.

On the 1000 mine goes on the same plate as everything else... I bolted a new cross bar to the plate for one side and used a longer bolt on the fuse box on the other side.

On the 1100G it's swapped with the CDI. The CDI now goes behind the fuse box / starter solenoid plate & the RR goes under the battery box.

Both look very stock in the end...

Is your bike stock or customized? If it's customized and don't mind making changes, Mount it somewhere it gets direct airflow over it. The are quite a few modern bikes that mount it up in front of the bike on the down tubes up where you would mount an oil cooler or a horn avoiding the heated air that passes around the engine. Some Hayabusa's mount them under the swing arm.

My 2006 Triumph T100 had it mounted right under the headlight. I was able to get the Sh775 on my GS 750 in about the same location but had to make some adjustments to the plate. so its still under the left side cover. I caught 2 screws and used some double stick tape

Mine is mounted under the right side cover on a plate where the original tool kit used to be.

I mounted mine on the back side of the original mounting panel. I elongated one of the holes on the R/R a little and used the existing mounting holes on the panel. I don't have an airbox, so I don't know how it would work with the airbox in place.

And if it were me I would locate the R/R as closer to the battery if possible if the stock location does not work.

Basically, a Series R/R will not get as hot as a Shunt R/R and so air flow is not as critical. These are apples and oranges comparisons.

It is more important to keep the voltage drops between the two as low as possible. This means shorter runs and thicker wires. generally, 14 AWG is good enough and about 1 ft runs.

If you mount the R/R in front you are going to go 3-4 feet each way (6-8 ft) total vs 2 feet. That means 3-4 times the voltage drop (ignoring connections).

Thanks guys.

You're right, mounting it on the back side of the original plate probably reduces the air flow over it, but it actually keeps the wires very short. And its convenient.
I think the biggest reason theres not much air flow over R/R is that I haven't gotten out to ride it in a few weeks. lol
