Need Help with Solid State Relay wiring
I have a boost controller that has 12volt two wire leads that go to a 12volt air solenoid. The controller can only handle a 3amp load. I need to control a device that has a larger load, so I am adding a Hella solid state relay... http://www.summitracing.com/parts/hl...FYQ-aQod4oUGNw
and I have no clue how to wire it in. Here's the Hella diagram. http://hellahd.com/index.php/default...001-931773987/ 30 goes to +battery lead 87 goes to +of higher current load 85 ???? 86 ???? I know its not the same as a mechanical relay so 85 and 86 is what I need help with. Keeping in mind my control wires normally open and close a 12v solenoid. I've gathered that 85 probably just gets attached to a chassis ground. And 86 needs to be a switched -negative. How do I achieve that with my current outputs?

85 is a permanent ground, 30 is the + side of the battery sized big enough for you load amperage, 86 is your control circuit(note it needs to be a negative trigger. 87 goes to the plus side of your load or whatever you are controlling.

Thank you now I just need to find out if my controller is switching both + and - if it is I'm golden. Just attach - to 86. If its not I will definitely need some help.

Your controller is switching the postive. Can I ask what load you are going to control with the boost controller that is more than 3 amps?
To do it with the solidstate relay you have, you would need another relay that accepts a 12+ trigger and then wire the ground through the contacts to send a -12 trigger to the relay you have. If it was me I would find a relay the will handle the current you need that accepts a +12 trigger. It would really simplify things. |

Just get a solid state relay with a higher current. Amazon has a million of them cheap. Depending on the load though you may have to add a heat sink to it.

Yes I'm looking for solid state control because it will be cycling millions of times. Not something you would do with a mechanical relay. Amperage of pump I am controlling is upwards of 20A
