(non)Charging system problem

[GS850Mike]

I got the new ebay reg/rec today. It looks nice. It has markings on it, LP2, or UP2. If it's warm enough, I may try and hook it up this weekend.reg rec.jpg

... something like this. It does both AC and DC current with the clamp on.

That is one heck of a deal for an AC/DC clamp-on meter.

Until quite recently, to get a clamp meter with DC amps, you had to spend over $100. I found one several years ago for $80, so I snatched it up. About a year ago, I saw an "introductory offer" posted on another forum that I visit, and got one for about $20. That same meter is now offered at the "reduced" price of $60. Accuracy is a bit less than I like, but comparisons with my calibrated meters at work at least let me know what to use for a correction factor.

Can you post more pictures please? Include the bottom and attached wires. If there are anymore marking please provide that as well.

I've never seen the LP2/UP2 before.

Thanks for posting these pictures.

Very interesting. That housing is a close approximation but they obviously did not try to do an exact copy of the compufire. For example there are 15 fins on this knock-off and only 14 fins on the original.

It would be very interesting to see how it performs with a current clamp.
If you don't have one , you might get an indication from temperature. The Series generally stay pretty cool (less than 100-110 degF) where as a shunt might get up to closer to 140 degF

Here is a picture of a real CF.

I have a clamp meter, when I get it installed, I will take some measurements.

Any updates on that knock-off CF?

[GS850Mike]

I haven't got it installed yet. One of the screws holding the battery box in is seized, and is fighting me getting it loose. GRRRR! Now the weather has gotten cold again so I probably won't get back to it this weekend.

Finally some nice weather on the weekend and I got the seized screw out. Removed the R/R and it looks fried.reg bolt.jpg

The stator will not look much better.

[GS850Mike]

That's not encouraging. Are there any readings I can take before opening it up?
