July 16, 200916 yr the 12volt line goes to your ignition wire either on the head unit harness or somewhere else so when you turn your car, it will turn on. Its says it in the diagram I linked.I know what it says, I was just asking someone who has actually dealt with the product and his experience with it so I wouldnt mess anything up. I also asked him because I know he has a lot of accessories and a relay to control them and didnt know if he ran it off that or what, I can read pictures and diagrams well just want a second input for me and my cars benefit.What size wire for the 12+wire and ground wire, appreciate it shizzzon.
July 16, 200916 yr this type of relay is used to prevent the front and rear batts equalizing with each other when they are not in use, IE car off just sittin there...I use a separate 30A relay on the HU's remote turn on wire to control over 50ft of LEDs and crossflow fans throughout the car. That's something different...When wiring the solenoids- Power in and power out is obvious.. use the largest possible.Ignition and ground wires are small. I used 16awg wire for mine.And to add to that-These solenoids are not specific on what terminal is what to a degree..You have 2 large posts and 2 small posts.The 2 LARGE posts are power inpower out. It doesn't matter which one you use for in or out and i'll get to that in a minute.The 2 SMALL posts are ignitionground. Again, it doesn't matter which you use for 12v ignition or ground. Just choose one. Whichever is ground, the other must be ignition. The reason why it doesnt matter which is power in or out is because when the solenoids are switched on via the key on ur car, the solenoid connects both large posts together so power can flow through both posts.
July 17, 200916 yr i really appreciate you all talking about this. its time for me to start thinking about getting a 2nd bat and isolator. fixed some of my confusion, thanks guys.
July 17, 200916 yr Author i dont run my system with the car off so i shouldnt need one a solenoid correct? Edited July 17, 200916 yr by Lucky 76
July 17, 200916 yr people always say that's the only purpose for them but it is NOT.The MAIN purpose of a solenoid is to prevent the front battery equalizing with the rear battery bank when not in use.My setup is a good example-My starting battery is 3yrs old and floats at 12.8v, made by PanasonicMy rear battery bank is 1yr old and floats at 13.1v made by PowermasterTwo totally different specs that you do not want joined together all the time.This is what causes premature battery failure.Keep them separated when not in use and they will have the longest life expectancy.

July 17, 200916 yr impossible!Whatever your battery's float voltage is, the alternator needs to be relatively higher than that to charge it.When comparing float voltage of battery to voltage regulator, the voltage regulator needs to be at least around 110% of the float voltage to charge and a max of 115% for best performance.For example-Older lead acid batts float at 12.6v110% at least charge at 13.8v115% charge for best performance at 14.3vFor 16v batts-I believe they float at 17.3vIf i'm right.. then-110% at least charge at 19v115% charge for best performance at 19.9v

July 17, 200916 yr u keep askin questions here and you will graduate from SSA-Express by the end of the month,
July 17, 200916 yr Author u keep askin questions here and you will graduate from SSA-Express by the end of the month, ahahaah ik i ask about 239487 ?s ... i have no1 to turn to but you guys ... online it is hard to find stuff in depth or specific to my need and in ct there is no1 at all to ask ... the shop i used to work at in high school was always trying to tell me stuff but it would always be wrong lol ... one more ? is this the isolator u were talking about from oznium? http://www.oznium.com/relay200 Edited July 17, 200916 yr by Lucky 76
July 17, 200916 yr Author yep thats the onek thanks 4 all ur help .... im sure ill b needing more lol
