    having some stuff added to my truck and im wondering if the battery the previous owner had in it is going to be enough for me. its a 88 chevy k3500 with the 454, running a meyers c8 plow (e60) with night sabers.On the roof i have a code 3 mx700 light bar with a built in arrowsitck in the back) im planning on probablly adding another arrowstick in the future but this will be wired into my brakes and 4 ways. may also eventually do leds( maybe strobes but i doubt it) in my taillights but thats probablly going to be it. Im aware the plow uses a lot of power so when plowing I will only run my 4 rotators on the light bar. but with what i have and what i may or may not add whay size battery should i have. the one in there currenntly is 630 cranking amps and im not sure if thats going to be enough. want to try to avoid adding a 2nd battery if all possible.

    Once the truck is running, it's the altenator that runs all of your accesories. If the alt. is not big enough it starts to draw from your battery. So if I were you, I would upgrade the alt. and add a second battery, and not have to worry about anything that way.

    Agree X 2.... One thing you can also do is to shut off the lightbar and just use the LED's... Unless your in a busy area... Check into the larger alternators like from an ambulance company... They should be able to match you up pretty quick.

    Good Luck!

    X3 on the alternator. Get at least a 100 or 120 amp alternator if you can. Your battery is a little on the light side too. I'd recommend 800-1000 Cold Cranking Amps. The comment on running your rotators only when you have to is sage advice. They draw more than anything else you've got right now. Depending on what kind of arrow stick you buy, they can draw quite a bit too. So be careful there.

    ok.Im not sure if its going to be a problem yet but was just looking into it. 2 new optima batteries and a bigger alternator, wiring them up, isolating the power, etc im looking at a $500- $600 project. its not my DD so its not of huge concern. im deff going to get a bigger battery and go from there. Ill check into the alternators though.Not running a lot of stuff so trying to avoid the 2nd battery if possible

    Except for that plow that draws 150-200 amps everytime you hit the switch. That's when the battery earns it's keep.
