Okay, I installed power lock actuators the other day. I know that they are wired up right, but I keep blowing a fuse!

The 12v power source for them is the one I used for the stereo 12v, the one that stays on when the key is taken out.

I tried putting a higher fuse in the fuse box, a 30 amp (normally a 15, will change it back soon), but then my in-line fuse for the relays blew (30 amp).

Is a simple fix just to find a new power source to tap off of?
If so, does anyone know of an alternate power source? Perhaps one in the fuse box?
If there is one there, how do I even tap into that? I have never done it before.

If you are wondering what year my car is... it is a 1990 civic hatchback.

 

You have a short in the circuit somewhere downstream of the inline fuse. If you want help, you'd need to be able to draw a diagram of your circuit, showing locations for the fuses, control unit, actuators, switches, and grounds.

 

here is my very crude paint diagram.
is this what you needed?
also, the locks worked just fine when the car was off the first time I tried them.

I did not install switches for them, it is wired to my command start.

 

To locate the short, disconnect each component one at a time, and then power the circuit. The disconnected component that prevents the fuse from blowing has the short. Start with each actuator and then each alarm lock.

 

so, i would disconnect one lock, see if it blows a fuse, then check the next one?

 

Yes, but start with each lock actuator in your diagram and then each lock-alarm unit.
