I have wired my 701 as per Z16 schematic for the Rotax. Up until now, as I have needed power to test the panel I have put my S700-2-10 switch in the middle battery position and then turned on the main switch for power to the main bus. Nothing remarkable happened. All was well. Now I am ready to start my Rotax 912ul for the first time. I put my S700 switch up to the full on “battery/alternator position”. OK so far. Now I flip on the main power switch as before to power the main bus but this time the 5 amp circuit breaker pops within about ½ a second. This has happened every time I have tried it. I spent several hours yesterday checking the connections to the S10, the S704 Alternater OV disconnect, rectifier and capacitor. They seem to be correct. Any serious rework would need the panel opened up. I'm talking “Can Opener”
Any thoughts on what wiring mistake could cause the circuit breaker to pop?
I understand what a difficult question this is to answer based on the info I have given. However, I'm hoping this could be an obvious “no brainer” fix to you experts. Possibly a common error for electrical idiots. Please phrase any advice as you would for a 5 year old.
Secondly. What is the downside of removing the S704 Alternator OV disconnect entirely…..Geoff
