Just as said in title, wired up and set to come on at 10 mph but will not activate selonoids.. I have tested it with test light and works fine... Acts like it can not support the grd.
Wire does grd when supposed to but just not working selonoids, I have hard wired them with power activated and works fine.

Any suggestions. or maybe another output I could use?

Or do I just need to use a relay?

Use a relay.

yep, you need to use a relay to support the current draw on the solenoids. They draw alot more current than the quad driver can supply. If you need a diagram, lemme know, it's pretty simple.

Thanks Guys,
Put one on - works fine now.
