My 77 Chevy c30 has no power. Jumped started it and drove it home. I turned it off then tried to restart it. No power no lights. nothing. Battery is good. An u help will be appreciated.


If the battery is good you will need to follow flow. Test light is the easiest to use. First hook light to ground and touch pos terminal,lights good next touch pos battery cable end, lights good. Next follow pos cable to starter pos terminal,lights good. Next hook test light to bat pos teminal,touch neg terminal,lights good. Then touch engine block, lights good ground. Next move test light clamp back to ground/neg side and touch alt pos terminal,lights good.if all that tests good, if all good move inside and check for power at ign switch pos term if at any time you dont find power you have wiring issue that needs to be addressed. Let me know what you find. Russ

I plug in rockwood detanator VII and it goes to protections mode


Generally if an amp goes straight into protection, the amp is not grounded well enough. Either you should find a new location to ground the amp to or unhook the power wire from the battery, remove the ground wire from the chassis of your vehicle. Strip the paint from the chassis, since it doesn't conduct electricity, and remove any corrosion or copper shielding from the ground connector. reground to a solid metal location Can be grounded to the brace behind the back seat or to the seat belt bolt for best results.
An amp draws a lot of power, there it needs to be grounded well.
Hook back up your power wire to the battery and see if your issue is resolved.

Have a 2000 gmc sierra ext cab pickup and two type R swr-1042d subs and would like to know the best enclosure for the subs to get maximum performance and the best ways to hook up a one channel mono alpine...


it depends on the amp what can it handle. will it do 2 4 or 8 ohm is it 1 ohm stable are the subs dual 2 ohms or dual 4 ohms. 1042s are dual 4 ohm subs so if you wire them both in paralel it will drop both subs into a 2 ohm load for each sub that is pos of one coil to pos of sec coil then pos to pos on amp and same with neg to neg to neg on amp. now if your amp is 1 ohm stable i would do both subs the same way you will get the most power out of the amp. but itll run a littl hot if you dont have adaquate power running to the amp. now i wanna think your alpine amp maybe only 4 ohm stable. i would run both subs like i had said pos to pos then neg to neg now both subs will be a 2 ohm load so what you do to bring it back up to 4 is you run the 2 bridged subs into a series which is pos from one sub to neg of the other sub the remaining pos and neg will run to the amps pos and neg. which will make it into a 4 ohm load. now the last scenereo is your amp is 4 ohm or 2 ohm stable. this is how to wire it to 2 ohms and not 1. take one sub go pos to neg then pos to pos on amp and neg to neg on amp this will make an 8 ohm load with one sub take other sub and do the same neg to pos on sub then pos to pos on amp and neg to neg on amp this will tell amp to run a 2 ohm load. 2 ohms is a good run for these subs if the amp can handle a 2 ohm load. now if you would have given the amp model number i could have looked it up to just give you what you needed but with this short info i gave all possibilities.

Diagram of 36 volt hookup for trolling motor, i have a factory 24 volt wiring in my boat and I need to turn it into a 36 volt please help thank you


To get 36 volts, number batteries 1 thru 3. connect pos 2 to neg 1, connect pos 3 to neg 2, connect pos 1 to trolling motor controller and neg 3 to ground on trolling motor.
This is only a solution for 3 battery system.
For 4 battery system, connect 4 to 3 pos to pos and neg to neg.
