Keep blowing fuse help!

  I  have put in my alarm and I keep blowing the fuse. All the options on the alarm work fine when I test them.Automatic doors , trunk, dome light, shock sensor, and hood pin. I will drive the car to the store 10 minits  away and all is fine. I will drive for an hour and all is fine. I stop and start the car and the fuse will blow with no rym or reason. The ground is good and the and the must power to run any of these options is the power trunk and I put a 15 amp fuse on this to be sure and it blows the 30amp main fuse. I contacted the manufacter of the alarm and they didn't tell me anything that I didnt try. Any help on this would be greatly apprec...

What alarm is this and what year, make, & model vehicle do you have? the12volt • Support the12volt.com

 I have the mannix sm700. It is in a 1991 pontiac trans am gta with no factory alarm. Thier website is www.mannixusa.com for more info. thanx

Does the fuse blow only when you start the vehicle or does it do it at other times as well? the12volt • Support the12volt.com

 No, the remote start option is not inst... it is standerd transmission and I didn't want this function. I use it as a traditional alarm. I don't know when it blows, it might be today or two days from now. I cant track it and I have looked and an electrition has looked at it all and all seems good???

That's not what I was implying. I was asking if the fuse blows when you start the vehicle with the key or at other times as well. If it's an intermittent problem, then it's likely you have a poorly insulated connection on one or more leads, specifically the main power lead(s) or any 12V+ output lead from the alarm or relays that you may have added. You'll need to comb through your connections and check each one carefully until you find it unless you can narrow it down more than you have already. the12volt • Support the12volt.com

I  only have one 12v+ lead out from the alarm. One relay for the doors,pkg. lihgts and engine kill. I dont know exactly when it blows, maybe when I start it, when I drive or when I stop the car.It is VARY inconsistant in the timing of when it blows that is why I cant track it.I saudered all the connections to  encure this wont happen. Could it be a bad relay and if so how do you check???

are you talking about the main fuse for the alarm???? where did you get your power from???Good Luck

 From a consistant 12v+ power source in the car. I was going to take it right from the battery but I was advised it wouldnt make a difference.
