I have a 1988 4runner. It has the 4 cylinder 22-re 2.4L. I currently have a stock alternator and 4 55 watt offroad lights already on the 4runner and working. I have a 500 or 550 amp battery. I forget which. I am wanting to add a possible 4 to 6 more off-road lights (55w) or (100w). i want to have 4 on a light bar and was wondering if 55w offroad lights are powerful enough to be on a light bar and provide any light. and i wanting to put to off road lights on the rear bumper for work lights kinda like on a tractor. What i want to know is this possible with the stock alternator and battery i have??? (i doubt it is)If it is not can you tell me what i need to make this happen and maybe a price range of cost involved??

Ive thought about this aswell and might have come up with a solution. Currently im running two 55watters on my bumper. But i wanna change them 100watts. then add another 4 when i get my roofrack. So heres what i came up with. Ive thought about adding a audio capacitor. These are added between the car batterys and the amps, and help the lights not to dim as well as no put a whole lot of strain on the alternator. So i hope it works. Just my 2cents

As 4xfred says, it al depends on how many lights you plan on running at one time. Only a few at a time, no problem. All at once, problem. You could get a high output alternator. Downey has a 110 Amp alternator that will cost you about 250. I think your stock alternator puts between 40 to 60 amps. N.W.O.R. offers 90, 130, and 150 amp alternators. There more expensive though at around 300, 430 for both 130 and 150 amp ones. Personely, I choose the Downey one. No problems at all. I remember someone pulled the alternator out of a celica or some toyota car at the junkyard that put out more amps. Don't remember what though.
A capacitor would help the dimming of the lights only when the radio is running. As carlos said, it goes between the battery and an amp. There are used to handle strain on the electricall system not full time, but in bursts.

MY celica has a 80amp alt factory, I have a seriousd stereo and run a cap and upgraded grounds. You can get a larger amp alt form anyplace that rebuilds alt's, depending on your alt you may be able to have yours respooled and get a larger amp out of it

Stock 22R/E alts are spec'd at 60A output @ 2500rpm+.
To figure out how much you are loading it use the formula Watts/Volts = Amps. For example a 55W light draws: 55W/13.8V=3.98A ~4A.
Start adding things up and remember you don't want to max the alt out w/accessories, it still has to charge the battery and support the normal vehicle loads.
The car audio caps are not applicable for this type of use.
You guys trying to light a stadium?

I deff. think you'd need a bigger alternator for that one.........or maybe an alternate alternator with some bike pedals hooked up.......just pedal reallly fast.....  |

I've got one of those flashing arrow retail signs you can buy. You can write your girlfriends name on it! It will get you just as much attention and look just as tacky as 10 offroad lights. I thought that was over back in the '80's. Next they'll be asking about chrome trim and neon shock boots. yuck!  |

Another thing you can do to help lighten the load on your electrical system is to run an 8 gauge wire straight from the positive lug on your alternater to the positive terminal on your battery. I've found that the weak link is the small wire running from your fuse box under the hood to the positive terminal. I have overheated this wire several time winching at night with headlights ect on. After running an auxillary wire, I have had no problems. Good luck with your lights though.... In my experiance, you just break them off when you really start off roading.  |
