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?



http://www.bandc.biz/pdfs/S701-1_Wiring.pdf



Pax,



  Ed,



  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.



  AHA! I see the point of confusion. The B&C wiring

  diagram cited calls for running a fat wire to

  the "starter contactor" which means the HOT side

  of the starter contactor which shares a connection

  to the ship's main bus. This isn't intended to

  imply that this contactor is used for starter

  control.



  The image might better read, "To main bus via hot

                                side of starter contactor"



  If you're looking for a starter contactor . . . I

  suggest you consider the S702-1 or equivalent.

Bob,



I noticed that crimp-on terminals were used on the solid leads on the 

diode.  It was my understanding that using crimp-ons on solid wire was 

not recommended.  Am I misinformed....again?

   Is that something I wrote? If it was, I cannot recall

   a context where that would be true. Here's a photomicrograph

   I just shot for 22AWG solid wire (diode lead) crimped into a

   red PIDG using an el-cheapo crimp tool.

   I couldn't find my polishing disk so the smoothed end is

   rather rough. Normally you'd be able to see the ring of

   tin plating on the wire at the interface between wire

   and terminal barrel. Nonetheless, this photo confirms that

   the two metals to be joined have been upset with sufficient

   force to make them essentially one with no voids.

I thought I saw it one of the electronics catalogs.  I'll do a little 

looking around and see if I can find where I saw it.  Thanks again for 

the info.
