I have an Aeroelectric recommended electrical system for a Rotax 912S with a S700-2-10 master switch that has about 350 hours on it.  I've recently been seeing the overvoltage protection light coming on periodically so today I went through the troubleshooting checklist for the Rotax alternator and regulator/rectifier.  When I got to testing the master switch the OVP would kick on an off when the switch was pulled and wiggled so I'm pretty sure the switch is bad.   Is that pretty common and should I be using another switch that's more robust?  Or are there multiple manufacturers of this switch, some with better quality than others?

   When you say the ov protection light comes

   on, is this the light associated with the

   alternator disconnect relay in the B&C

   PM alternator control kit?



   The 2-10 switching protocol is offered by

   many manufacturers. If you purchased the 2-10

   from B&C, then it's a Carling with riveted

   fast-on tabs. It may be that one of these

   joints is loose. I'd like to have your failed

   switch for analysis.



   I'm forwarding a copy of this to B&C. I think

   they'd be happy to send you a new switch if

   you send the old one to me. We'd like to know

   what's going on. Will report finding to the

   List.



   Give Greg a call at 316-283-8000. Send the

   switch to Box 130, Medicine Lodge, KS 67104

Thanks Bob.  Yes, I have the disconnect relay kit.

I'll get a hold of Greg and then send you the switch after I swap it.

I must not have good luck with switches, the first ACS key switch I had was bad right out of the box.  The replacement they sent was just fine.
