Hey Fellas im having trouble with my 4 door blazer I have a 3500 watt amplifier for my subwoofers, a 90.4 for my mids and highs 4 agm batteries in the rear, 4 0gauge wire runs front to back, and a 270 amp alternator but today i noticed that one of my batteries somehow moved and the wires shorted out over night... thankfully all my amplifiers and everything is okay but now when i put the key in the ignition everything turns on but there is ZERO sound of my truck trying to start at all..... any help on what could be the issue??


I really do appreciate the help very much!!

 

well not sure what your problem might be but here is something to try charge your battery up and try to start again if you still have the same problem with a good charged battery have someone turn the switch and hild it and take a rod or hammer and tap the started it may be stuck witch would your starter is on the pasanger side of your vehical you should see it through you front right wheel well try that

 

alright well , i checked each battery and they are all fine, i have enough battery juice trust me.. i took out the square fuse under the hood on the drivers side and i could start the truck if i bypass it with 2 wires.....

 

okay so this is exactly what i did, i left my keys with the ignition on the "on" position, i went under the hood and took out the "starter" fuse and when i bypass it i get 2 wires and connected # 87 and #30 together and it will start up right away.... could it be this fuse not working?


i know #30 is constant power, i checked that with my dmm

 

well there you gofuse burnt up lol replace to and see what happens also do you have these batterys all conected you truck is made to run off of 12 volts and belive it or not haveing 2 12 volt batterys does not make a really strong 12 volt it creats a 24 volt battery if the makings for a buntup wireing heanes or worse your whole truck could catch fire thats if ther all conected i could see it working right if the altornator was just charging the other batterys and it was not running anting other tan your sound system just my 2 cents

 

well im working on having a bracket made to fit 3 alternators, maybe then ill run 2 alternators to run the system and 1 for the truck, but all my batteries are 12v and they are wired in parralell when my truck starts, my high output alternator is set to charge at 14.8volts.

 

i dont think its the fuse though... it seems more like a relay.. what is it?

 

to be honest i think its my ignition that doesnt work...................... somone please help.. its wierd that my ignition wont start it but when i wire #30 and 87 with the ignition on, it starts right away ! :/

 

o so when you jump the wires it starts up without you turning the switch.?

 

yea as long as the ignition is in the "On" position i touch those 2 wires and it turns on and it stays on......
