Electric trunk release

[Gumby]

I bought 2 electric trunk releases off ebay a few years ago. (at different times) They both bolt up to my 72 Challenger trunk support just fine, both have free moving solenoids, and both work with the key. yet both will not pop with an electrical charge.. I wouldn't think 2 could possibly be bad. They both look brand new. Am I missing something simple? I have no idea what they came off of, but they are both Mopar, and fit the regular trunk release perfectly.

  Mystery for sure... do you have any pics or wiring diagrams?  Did you test them (put power to them) before you installed them?

Did you make sure they have a good ground?

Yes, I hooked them directly to battery power with jumpers and nothing. Used a battery charger and tested again and nothing. I was wondering if there was a relay or something, but the solenoid lead is kind of small, 18 guage or so, so wouldn't be able to handle a lot of current. I need to test them with an ohm meter, I guess.

I'm not familiar with these solenoids.  How many wires are there?

There is a member here, Goodysgotacuda, that has installed solenoids in his Cuda.  You might want to PM him, he's pretty smart!

The mounting bolts are what need to ground the solenoid. I supply mine with a relay in the car, however that doesn't have anything to do with you jumping power directly from a battery to it. Certainly check the resistance between the lead wire and the steel where the bolts mount the latch.

I wouldn't say all that!

I've smoked a couple of those when my cheapie car remote buttons got pressed while in my pocket. The coil gets hot then smokes the enamel coating and heats up the platic tube that the rod gets pulled down into.  If yours fried, it wont slide up and down easily.

That coils uses a good amount of juice. You using a car battery with your jumper wires?

ShelbyDogg, yes, I had it hooked up to straight battery, then the battery charger set at lowest settings. The plunger in both of them freely and easily is pushed and pops back out no problem. haven't had time to check the coil on an ohmmeter yet. Will do tomorrow.
