hi bob,

 i am trying to do ov protection on a viking 110. b and c would have the ovm blow a breaker and cut off current to coil in a relay. i think i have seen drawings of yours where a contactor is used betweeen alternator and main bus . can you direct me to a drawing that is as simple as you say. any current for relays/ contactors would have to come straight from the alternator. worst case with the honda is that both batteries must be taken off line, leaving the alternator to provide spark.

 thanks, bob noffs

well, i guess i should wire in a crowbar. seems like it should be pretty straight forward to have it break the circuit to the field. i will take a look in bob's book for ideas and go from there.

  The crowbar ov protection module can be added to
  any system wherein alternator field power is
  taken through a typical 5A breaker. The
  module is wired from field supply line to
  ground at any point downstream of that
  breaker. You can find examples in the Z-figures.

I'm not (either) Bob, but...

I assume you're talking about an internally regulated alternator. If you have a copy of the 'Connection, go to drawing z13/8, 'all electric plane on a budget'. You can copy the circuit shown for the Dynamo (upper right hand and top center of the page). Just erase the dynamo/regulator parts and the filter capacitor, and tie what's labeled as a red wire at the voltage regulator to the B lead of the alternator.

Bob Noffs,
Here is a link to Bob's drawings:
http://www.aeroelectric.com/PPS/Adobe_Architecture_Pdfs/
It is OK to mix and match desired features from different drawings.
Z-19 and Z-24 might be useful for you.

That will work if he has a dynamo with the B&C regulator, but that

drawing doesn't interrupt the B lead of a regular IR alternator. I don't
think he spec'd which alternator he's using.

Z-19 has dual batteries and a single alternator, which is what Bob plans for his Viking. Z-24 has a contactor in series with the alternator "B" lead.
