wiring my service van

I recently purchased a 1993 Ford E-250 service van. It's one of those with two front seats and nothing else but cargo space.

I use the van in my computer repair / home theater installations company.

I have plans to purchase a shelving system for the back end. I also have a stereo system(500watt amp & 2 subs included) that used to be in my personal vehicle which I plan to install soon.

Eventually I would like to have the ability to charge my drill batteries in the back of the van, as well as possibly have a wireless printer in the back so I can print from my laptop. I will also be eventually getting a security/remote start system for the van.

With all that said, here are my questions: 1) will the stock alternator be adequate for all my plans? 2) will one battery be adequate for all my plans? 3) if I do need a new alternator and/or battery, what would be the best way to wire all this up? Please give me examples of specific equipment that could make this possible. I know I will need a good quality power inverter for instance.

PM Oldspark on this but to be on the safe side I would suggest a twin battery split charging system to run the audio and your rear accessories.

Amateurs assume, don't test and have problems; pros test first. I am not a free install service.
Read the installation manual, do a search here or online for your vehicle wiring before posting.

Nah - don't PM.

I was waiting for others else it got close to off the latest-100 page with zero replies.

I'd need figures - like expected demand etc.
Also current alternator rating - though strictly speaking, how much it has in reserve (ie, what the vehicle requires to run...)
But those figures and reality vary - eg, a 120A alternator running mostly at idle is very different to "often" 2k or 3k RPM etc.

But yes - I definitely suggest a second battery with an auto isolator. Hence independence - ie, can crank and start despite flattening "the" battery.

What model alternator? Or is it a single wire (D+) type, or multiwire with (say) "S" & "L"?


Charging drills etc should almost be negligible unless a lot of charging or using an inverter (with high standby current consumption etc).
12V chargers are more efficient, but I'll use inverter & AC chargers unless I get 12V chargers cheap or if my battery/system can't handle the inverter.   (EG - why spend $1,000 EXTRA for a fridge? When the extra solar panels plus the extra battery etc required to (maybe) keep the old fridge going cost about the same.)


Actually - is solar and option? Though if you are starting/charging every day or two (when "working"), solar, winds etc is rarely an economical option. (A green option, yes.)
