Hey Folks,
We have a 64 Cherokee 235 that we just did some electrical work on and now we've got a crazy ammeter bounce.
We had a starter issue so we replaced the stock starter (a rebuilt from the 90's) with a Sky-Tec. While we were in there, we replaced the starter solenoid, the master solenoid (attached to the battery box) and a new battery.
Now, when the master is on and the engine is running on the ground the ammeter looks like a metronome bouncing from end to end at about 200 beats per minute. In the air and apparently with some manifold pressure it settles down where it's supposed to be (around 20 amps).
I haven't done a ton of testing yet - going to go out tonight with my CFI to get night current and he's an A&P so maybe he'll have some thoughts but while it was bouncing all over I was shutting everything down - strobe was off, nav lights off, radio stack off...nothing stopped the ammeter bounce.
I've read a few things - some folks say replace the master switch, others say get under there and clean up the connection points. Curious if anyone else has seen something similar and has any ideas?
