 |

Bob,
I have seen in several documents that you say it is okay to switch the fat wires on the S701-1 contactor - which I would like to do.
My contactor looks like this: http://www.aeroelectric.com/Pictures/Contactors/s701-1.jpg
What would be the proper way to handle the diode and jumper wire?
Thanks
Sam

You need to reverse everything in the picture. Diode
flips over, jumper wire moves to the right-hand terminals,
battery fat-wire now goes on right fat terminal, system
fat-wire goes on left fat terminal.
Alternatively, you can simply turn the contactor around
on its mounting bolts and leave it wired as shown in the
photo.

Good. I didn't know if it was all interchangeable in the innards.
And I guess you answered another question, that gravity and vertical orientation has no real effect on the successful operation of the solenoid.

About the only time you might want to consider orientation is in the
unlikely event that the solenoid return spring should fail. It would be
nice, then, if you could have gravity (or centrifugal force) working for
you to open the contacts.

I've never seen one fail. They're very lightly stressed.
I've seen them corrode . . . but then after water enters
the device, worrying about spring corrosion is the least
of concerns.
There's a lot of mythology circulating around about
"proper orientation of contactors with respect to
g-loads" . . . This has been debunked several times
and can be reviewed in the archives.

On this topic (kind of), I have a S701-2 but now am only going down the single Alt route. Do I need to remove the extra diodes for it to work properly as (effectively) a S701-1? I presume that they are the same internally.
Many thanks,
Derek Sington

Thank you for the swift reply, but would you mind clarifying? Am I correct in assuming that I need to remove the diodes (in which case the photo of the S-701-1 on B&C's website seems to show only one diode with just a wire going from the side contactor to the front contactor.
http://www.bandc.biz/s701-1l.jpg
Or can I simply leave the S701-2 as-is?
Sorry to be a pain!
Many thanks,
Derek Sington.

Wire per the schematics and pictures. You need
a jumper and one diode for a battery contactor.
