REFLECTOR: Using the starter supply(+) wire as a charge wire

[Terry Miles]

Scott,

 

It looks like this:

http://www.bandc.biz/cgi-bin/ez-catalog/cat_display.cgi?7X358218#c905-100

 

There is a hold down base for it that is a separate purchase.  If the link
fails, try B&C and scroll through product categories to current limiters.

Terry,

this what you mean by current limiting device?

_Fuses_-z-_Disconnects/Fuses_-a-_Fuse_Holders/Current_Limiting_Class_RK1/LEN
RK100

or this?

Thanks,Jim.  Sorry.  In a earlier post about this I mentioned, there will be
an 60a ANL current limiter between the B lead and the wire run back to
starter lug.

You can do this however remember that the starter cable is like a welding
cable and without any circuit breaker protection so a short will cause a
fire!  That is the reason for the starter relay to minimize the length of
the unprotected wire.  You normally have a CB in the alternator power lead.

I talked w/ Skytec starters today.  On their web site they talk about an
alternative wiring scheme that eliminates the normal firewall starter
contactor which is required on certified span cans.  I can wire my starter
button directly to the coil/contactor that is bolted to the Skytec starter
instead doing the conventional route of contactor in the nose that then
ports juice to the Skytec contactor and its starter motor.

 

Terry;

 

I don't know about the Skytec, but typically the solenoid/contactor on the
starter takes a significant current, and has a very large in-rush current.
I think you'd would want a switch rated to 30-40 A; with spike suppression,
for reliability.  I used a automotive 40 A relay for the job (also with a
TVS) so I could use a light duty push button up front.
