Bigger battery cables. I went with 1 gauge welding cable for the starter and main grounds and 4 gauge for the 8 gauge wire running to the starter relay.
"Big 3 upgrade." This is an upgrade that kids with obnoxious stereos do. Right now, the link between the alternator and the battery is a 8 gauge wire that goes through the starter relay, a fusible link, and then a 10 gauge wire to the alternator. This is a weak point. Bypassing that and grounding the alternator and chassis better are the "Big 3"
Dedicated grounds. Best thing I did. If I had to go completely back to like it was when I bought it except one thing, I'd keep the dedicated grounds. Silly electrical problems just went away and when I do have an electrical problem, I know it isn't the grounds. http://www.jeepforum.com/forum/f8/be...1/#post7724128
...While I have that and the fan shroud off, what else should I work on? The jeep is not moving anytime soon while I work on a new cj style dash....Its a 1990 with 150k miles. Water pump? Thermostat? Belts?
Belts and thermostat are a good idea if they are unknown age or belt looks bad. I wouldn't replace anything else unless they look old/worn/cracked or otherwise 'bad'.
However, I would like to see pics of the CJ dash
