How to hook up 3 wire trim to 2 wire powerhead

The relays will work but you have to keep the coil side 12 volts, the contacts can handle the 24 no problem, plus with 24 volts, the amp will probably be less.

Confused bout the "coils"?.....I'm not looking at the control box but wouldn't one have to supply 24v to the front side of the relays thus making the whole panel @ 24v? This is an OMC trim unit if that matters at all......maybe staring at it when I'm having this convo would be a but better cause I'm starting to feel like a moron and I somewhat know what I'm talkin about, sometimes lol!!

Double the voltage across the saame resistance equals half the amperage. I think.

I know for sure that applies to ac current. I didn't know enough about dc current to make that statement. Now I'm curious to know for sure.

Your control circuit is completely independent of the controlled circuit. 12 volts dc can activate a 230 volt ac circuit.

The power feeding the relays from the trim switch needs to stay 12 volts.... the trim switch usually is fed from the trim relay box on the motor, so you will have to separate the red wire feeding the trim switch.... that can be done on the omc's inside the relay box.... you will see the three wires that feed the trim harness going forward, just remove the red wire and put it on 12 volts then take the heavy red wire from the relay box off the starter solenoid and hook it to 24 volts.......

That only works with the difference between a 12 volt motor and 24 volt motor...... keeping a 12 volt motor and adding 24 volts to it only makes the motor spin faster and in most cases draws more amps too

I will look into that....thanx!

Got a little somethin something in the mail today.. Thanks again Quinten, they are installed and working perfectly.

I'm not saying there are any "know it all's" here and I'm definitely a "know a little" but I'm glad it was enough to help and glad I could do it. I'll take good news any time!
