On my last few flights my charging system would not start charging until a few minutes after starting. Then it would begin working normally.
Today I decided to move the regulator inside. I did the move but did not mark which of the two white wires went to the R terminal and which to the B terminal. I figured Vans instructions would cover that when I got to reinstalling them. Wrong. I guessed which way they went. Turned on master and the 30 amp fuse blew. I replaced the fuse, swapped the position of the two white wires, turned on the master and the fuse blew again.
With the old Skyview wiring diagram I have I cannot follow the P156 circuit that carries the two wires from the regulator to somewhere??
I have done two tests:
1. With ohmmeter from the wiring connectors to ground. No contact with the two G blades or the C blade. With both R and B initially 50 ohms building quickly to near 200 ohms and then nothing.
2. With voltmeter from battery positive to the connectors. 0 volts for the two G blades. 12.9 volts for R&B blades. 9.5 volts for the C blade.
I have evidently caused a short somewhere but I do not understand the charging circuit enough to figure out where. Can someone out there help....please....
Incidentally, in doing the move I noticed that the B wire was not fully seated. So I am hoping that was the root cause of my initial charging problems so I am not working on moving a near deathl regulator.
