I know Dan posted about a 150AMP alternator....this is along the same lines.

I am planning to install a set of, possibly 4, lights up high, roof mounted on my 95RRC. I already run 2 Hella Black Magics on the front bumper. I am wondering if the OEM altenator can handle it?

Alternatively, should I:
a) replace the alternator with a higher amp model - which one, what size?
b) put in a dual battery system?
c) Only install 2 lights up high?
d) A, B and C?

Cheers! :drink1:

I just got my 200 amp Mean Green Alt last night, I'll let you know how it goes.

Jonesy, you can determine the WATTS by this means.

Amps x volts.
150 amps (alternator) x 14v = 2100 watts.

You can also add all your lighting in watts, then divide into 14v.

Say 200 watts (100 w each lamp) / 14v = 14.3 A.

Ideally you want to run relays for your aux. lighting, I prefer to use large gauge wiring. Its overkill, but voltage drop on a thin wire is not something you want.

Make your own wiring, as the relay harness in most lighting kits is puny.
