Time for an update.
Received shipments from my auction site orders:
1. Spare K8
2. Better multi meter with amp clamp
3. NOS Weller Solder gun (new in box, but old model which had been sitting in an estate sale). Wow, it works great!
So to the generator...
In previous posts, I detailed removal and cleaning of K1. Last evening and today I performed burden resistor test by un-soldering and resistance testing. I also swapped the K8.
1. Burden resistors all tested out and were re-soldered with the new gun. Did I mention that thing works great compared to my 40 year old pencil type iron?
2. Swapped K8 and set up for load test... same dismal results. O/L tripped after some time at higher loads.
I will say it seemed to run longer before tripping. The "floor" seemed to be closer to 60-65% of the load meter instead of 50%. However, the same result. I even reset everything and ran a second test ramped right up to 75% and then cycled a burner that took it up to 100% intermittently. It tripped within a few minutes on this test.
I'm thinking my K8 is fine and I now have a spare. I'm leaning towards a problem with the CT and/or the the wires that are wound through. I'll have to do some reading this week in the TM on test procedures for that component. Just thinking out loud here, could this still be an issue with K1???
Thanks in advance.
