With my Warn winch now, plus a generator that isn't totally reliable, I'm a little nervous about being out in the woods and running the battery down to where I can't get started. Do any of your guys carry and extra battery? If so, is it "in-line" with the charging system or will it keep just stowed in the back somewhere? |

i run a delco-remy alternator, and i have the biggest deep cycle marine battery i can find. my biggest concern is having a break down in a busy intersection, with the deep cycle i can at least crank it to safety if i need to. another thing i did was put a high idle solenoid on my carburetor, you can get them of mid 70's ford and amc carburetors that had air conditioning. you can do the same thing with a throttle cable, but with the solenoid you get the same bump in idle every time you push it. i don't have a winch yet but i am preparing for the extra demands of one. (also seriously considering on board air and a york compressor) in my opinion an extra battery adds a lot of weight, and if improperly stored as an auxillary it could become a fire hazard.

If you are not hung up on the looks of an alternator, it is a much better solution than an extra battery. The alternator is half (or less) the weight of the generator and you are not packing 50 lbs of extra battery. A 63 amp Delco SI 10 or any of the Delco SI 12's are an easy install, pretty much dirt cheap, available everywhere, and last a really long time. I have a 63 A SI 10 on the CJ 5 that has been on there since about 1970 and used the same on my 3B for 3 decades. Both have electric winches and never have had a dead battery due to charging issues. In 5 decades of wheeling, I have yet to be stuck in the back country from a dead battery (knocks on wood). That said, I do park them facing downhill if possible-just in case. Just get a good battery. And I no longer consider the Optima's as a good choice. Really poor performance on the last red top which was replaced at 2 years. |

Thanks Duffer for that suggestion. Does changing to an altenator also require a different solenode or voltage regulator. I read somewhere that a custom bracket is available for the switch-out as well. |

Goose, I assume you are already 12V with the charge indicator light in the instrument cluster so you could go two routes: 1) standard SI 10 or 12 with internal regular and hook up using existing idiot light and stock wiring with a little modification, or 2) a one wire version of the alternators where you only need to hook up the battery connection. If I was going with this, I would want either an amp or volt gage to keep tabs on the system. The only down side of a one wire is that you need to bump the rpms a bit once to excite them but that is usually not a problem. Either route, you should be running at least 10 gage wire on the battery terminal, with 8 or even 6 gage desirable depending how many amps the alternator is rated for. When using the winch, the alternator will be at full output and 60 to 100 amps in 10 gage will make for a rather warm wire. |

X2 on the alt conversion, easy to do. One wire hookup- regulator is internal for the delco 10SI alternator. be sure and get at least a 60amp alternator so it charges the batt fast to keep you pulling all day long. But if you go with the extra batt be sure and get a batt isolator too. Tons of info on the web about this conversion. http://z4.invisionfree.com/CJ3B_Bulletin_B...?showtopic=2834 |

I forgot you'll need a wide pulley on the new alt too, most any auto electric shop can fix you up with the internal regulator and pulley for your alternator. Meaning you don't have to buy a one wire but you would need to convert the alt you get using the parts from the shop. |

Before you buy/find a B belt pulley, check to see if the one on the generator will fit. Not sure about Autolite generators, but most of the Delco ones have the same pulley ID as the alternators and can be directly swaped. |

This is probably a dumb question, but are booster packs a viable back up plan? With winter closing in I was thinking of writing a note to Santa http://www.ebay.co.uk/sch/i.html?_nkw=jump...5991_2113181&tt |

I am thinking long term fix, but Phil's idea would get you back up and running if you zapped the battery with the winch good idea Phil. |
