Stator install

Thanks for the info guys. Will the '06 rectifier will fit on the '05FJR?

I'm going to make it fit! I'm tapped out right now and no time so it will be Nov or so before I get around to it.

Had anyone paid attention to the stock stator under these same conditions? Or now that you have the ESG installed are you aware of the difference in readings in the extreme heat?

With this in mind I paid attention today and found the following:

Ambient air temp about 90.

No driving lights, heated gear etc on.

high beams ON

Idle is approx. 1100 for all readings

Volts at idle when I started it in the garage: 14.2

Volts at idle when up to operating temp.- 2 bars: 14.0-14.1

Volts at idle when hot- 3 or 4 bars: 13.8

Volts at 4000 rpm when at operating temp: 14.2

Volts at 4000 rpm when at 3 or 4 bars: 13.9

When I say 3 or 4 bars I mean this; It was a 4 bar day here sitting at a stoplight. It would go to 3 bars when the fan ran long enough and/or I cruised a bit after the light went green.

FWIW...

I would suggest that the above voltage difference is due more to the fact that the battery is becoming more fully charged and the regulator is sensing this and cuting back the output rather than the temperature of the engine. Was this part of the test performed by starting the engine & letting it warmup by idling and noting the voltages? If so then perhaps it was becoming recharged after the start. If not then my theory may very well be incorrect.

The day that I noticed the drop when the fan came on I had ridden the Dragon & mountains all day & became stuck in traffic at Pigeon Forge, TN. I had the J & M on, Escort 8500 on. My Escort was in the "show voltage" mode and the pickoff point is at the rear tail light circuit which always reads a little lower than the true battery voltage. The ambient temperatures were very near 100 degrees. It was a very miserably hot day & I'm sure the battery temperature was significantly elevated as I had been stuck for what seemed like hours (probably 30-45 minutes). At the time I turned off the J &M even though it has a low current draw in the receive mode. I was getting very concerned that the cycling on & off & long fan run times were going to kill my battery in the traffic. It didn't happen, but, I was seeing below breakeven charge voltages even taking into account the voltage measuring point. I wonder if anyone on the board has checked how hot the battery itself actually becomes in sustained high ambient temperatures and low or no speeds such as the above as I am fairly certain that the efficiency drops off with higher temperatures I just don't know how much.

Thanks for the info Blueliner

Here is how it went. I started it let it come off fast idle and drove it out of the garage. So recharging took place quicker than it would have otherwise.

If anyone can think of a test that I can do, let me know. I'll give it a shot when circumstances permit.

Thanks for the continued info guys. Maybe as it gets cooler in the coming weeks we will see a positive result.
