hi i have install a door popper kit to my alarm on my holden rodeo 1988 tf ute it is set up so when the 2nd unlock pulse goes the drivers door pops open and another trigger open the passenger side door..

the problem im having is the button i use in the interior ive set up to pop the door has to much power going through it.. i think its only rated 15amps so it keeps frying and i really want to use those type of buttons...

this is how its set up now

my question is would i be able to set it up this way to have less power running through the button or would this fry the alarm system or something bad.

oh... and if the second diagram works how do i reduce power going through the button? use thinner wire? or use a fuse as shown.?

and should there be a fuse running on the +12v constant line before the relay for the solenoids or should i just leave it unfused.

im quite new to this stuff and any help would be great. thanks

wire the button to activate a relay as well

or you could probably have the alarm and the button each activate the relay using diodes for separation. someone else please chime in i'm about to run out the door to work

Most alarms use negative pulses for the lock and unlock in relays that change the pulses into stronger 12volt signals, why dont you wire the button to send a ground to the 85 of the relays. The second diagram is right except just take the power supply off the other side of the button and ground it instead and fuse the 86 and 87 to 12 volts with 15 amps and leave 30 its good.

That way no power is going through the button at all just ground.

oh ok thanks for that.. will give it go. does 87a need to be grounded though?

I would not hook 87a to anything.

Maybe its just for actuators that it needs to be grounded try without first, just makes sure you put the fuse though
