77 Scout II with 345.

I'm going out to replace my broken tranny cable. While I'm out there I wanted to figure out why my reverse lights aren't coming on. I wanted to check the switch first before getting out the meter and searching for current.

Anyone know where the switch is so I don't have to search? Is it under the transmission arm cover or somewhere else?

By the way, my alternator isn't cutting it. I have a non-A/C scout, but when it hits -40F my baby has difficulty turning over....even with a core heater and proper oil. Also, when I turn it over, everything has to be off, the lights, the radio, the heater fan, etc. (I haven't gone and looked what I have, but I'm pretty sure it isn't a 63amp). I'm interested in the Mean Green alternator at 140 amps. Anyone have experience with these? I want to put a winch on eventually and put in an amp with a subwoofer, so I'll need the power.

Thanks.

There is a small switch for the reverse lights. Check under the tunnel cover, that's where mine sits. Has two wires coming out of it, one for power in, one for power out. It is the same style switch as the neutral safety switch, so if your climbing under it, follow the wires, you should see two sets, follow them both and you'll find your switch.

As for your alternator & start up, that has NOTHING to do with the initial start up. I recommend that anyone that see's -30 or colder (I live in interior Alaska, so I know cold); use a block heater, oil pan heater and battery heater. Your battery is too small (in CCA, Cold Cranking Amps), that's why you're having issues starting. For your area, you should have 1 CCA for each Cubic Inch Displacement, then 300 CCA additional for a MINIMUM sized battery. Choose the largest CCA battery that will fit into your battery box (or tray). My '74 runs a 950 CCA battery & that turns over my straight 6 at -50 after sitting a week like it's summer time (even when I don't have it plugged in). I have the stock alternator, but may upgrade as I have a plow.

For the mean green, I've heard good and bad. It's up to you, there are larger alternators out as well. I've seen some 240A ones out that can be utilized in the Scouts.

For what you'll be adding, the alternator upgrade is recommended. There is plenty of information concerning the upgrade already on the forums.

Start w/ the battery, then look at the alternator. Good luck w/ the scout.

Thanks.....that's very helpful. I'll go to Interstate and get a BIG battery. Maybe I only need to upgrade to 63 amps at a lot less cost. I can probably take the stock one in and have it upgraded for the time being. When it comes time for the winch maybe I'll lay down the cash for the higher amps.

You should be able to find an electrical rebuild shop that will rebuild your stock alternator to your specs. I lived in MI for several years and there were a few guys that could take a stock alternator and get 95+ amps outta it; it was a custom wind, but may be worth your effort.

Interstates make a good battery. Good luck with your Scout.
