Howdy,

I just recieved from B&C a starter contactor S701-1 which, unlike all
the others I've seen, has plastic covers on the mounting tabs. Where is
this guy going to get a coil ground connection? Is the intention to wire
through the switch to ground?

Pax,

The S701-1 is a continuous duty battery master
contactor and not intended for service as a
starter contactor. This is why it is shipped
configured as a Battery contactor which gets a
ground through the battery master switch.

If you wish to use this contactor to control power
to your starter, you remove the jumper wire installed
and run your starter push button to the left, small
terminal. You add a longer jumper from the right,
small terminal to ground.

My bad. I meant to say battery contactor, not starter. After I posted, I went out to the shop and verified that the small terminal on the right closes the contactor when grounded. For some reason, I had pictured putting voltage to the contactor to close it instead of pulling it down. Duh, where do I get power to the switch to close the contactor if the main bus is not hot? Didn't think it all the way through.

No problem. But your query did get some
attention to a need for better labeling
of the contactor's downstream terminal.
