    Default Is a batt cable needed

    If you have your starter connected straight to your battery do you need to still connect a battery cable to the external starter soleniod.. I mean its only a 8 gauge wire that feeds your instruments and ignition ??? Or will it draw too much from the smaller ignition wire at start up...

    So can i just run a 8guage wire to the soleniod and call it good or am i going to have to run a big ass cable

    Which engine and does the starter have a solenoid bolted to it?

    I've never understood why people run them that way but yes it will work so... you're going to want a "full sized" battery cable going from that Ford solenoid to the Chevy's solenoid.

    Im not running my cable through the soleniod. Its direct off the battery to the starter, but im using the start wire from the ford soleniod to the starter soleniod, and just basically giving power to the dash. I will grab a pic and show you what i mean

    If you want to use the solinoid on your starter, and not the external one, consider this. Lots of boats only have a 10 ga. wire for power going to the front to the dash. The solinoid wire is only a 16 ga. or so... this wire needs to be 12 or 14 ga. minimum, to get full voltage to the solinoid. Voltage is traveing in excess of 30 ft to get to the starter solinoid. This is why many employ the external solinoid, in addition to the starters with solinoids. Much less voltage drop is a direct result of the external solinoid.

    I want to run the 8AWG wire to where my finger is pointing.

    And then run the cable from Batt to starter, eliminate the big loop...I have already wired the start wire from the soleniod to the starter isnt this like a cars wiring (Close)?

    So since the boats ign and instruments run off a 8AWG wire hmm am i light ing candles in the wind again

    Steve, the wiring should go; from the battery+ terminal with a cable to the large lug on the starter, from the large lu on the starter with a #8 to the power side of the slave solenoid, the other pole of the slave solenoid (can be as small as say a 14 ga. wire) goes to the "S" terminal of the starter....

    The idea is to eliminate the voltage drop from the key switch to the solenoid on the starter to get full voltage which brings in the bendix.

    Think about it, the power comes from the battery, goes all the way up to the dash through a key switch and possibly a neutral safety (probably not most jets) and back to the starter solenoid, that could be like 30' of wire...If the bendix does not pull in fully and spins, it could break the nose housing of the starter, that will piss anyone off...

    Yes you can run 8 ga from the dash to the Ford solenoid and 8 ga from the Ford solenoid to the Chevy solenoid.

    From my experience the Ford solenoid can be eliminated by using larger wire on the key switch supply wire and the starter wire coming from the key switch. Alternaitvely you can eliminate some hard start conditions by adding the Ford solenoid to the system.

    2sav, your setup will work and is one way it has been done for decades. It is not the most effective use of the Ford-type starter relay, however, since all you are using it for is to trigger the GM starter solenoid.

    WTF? 8 ga is plenty big enough wire to run that Chevy solenoid by itself, if you would like to.

    Thanks guys ..

    I just think it would keep it simple and clean.. I started to look at the Eliminators wiring with double batt and thought F-that looks like a rats nest...
