Wiring Power Inverter to Ignition
Thursday, September 20, 2012 9:01 AM
I am installing a power inverter in the trunk and want to wire it to the ignition to avoid having to manually turn it on and off. This is how its currently ran.



What would be the best approach on doing this?

does it have a separate on/off signal wire like an amp? if so, run that wire to your wiper fuse. if not, depending on the amp draw of the inverter, run a relay or solenoid fed by the battery and triggered by the wiper fuse.

Id run from a switched source to a relay and then from the relay to your inverter.

If that thing has a power switch you can tear it apart and wire it up that way, otherwise you need a heavy duty solenoid to switch the power feed going to the inverter.

If you want to go that route go to a tractor implement (being serious here) like Case IH ( I work at one) and get a "cab solenoid" for a 7130 tractor. it is made to switch constant power with heavy draw without overheating and etc. The only flaw i see to this plan is.. well that solenoid costs like 4x as much as that cobra inverter so I doubt your going to go that exact route.. Oh well. thats my two cents.


Have a nice day.

So after some thought. Im going to tap into the switch contacts and run a relay off the ignition. That way it flicks the power on and off.
