Of the upgrades I’ve done on my '02 cauck (CArt-trUCK), the one I should have done first was…
wait for it…
…the headlights. Good god the stock headlights absolutely sucked ass.
Followed by the taillights, those needed LED too.
I bought mid priced Chinesium LED headlights that would fit the existing holes and they are better than stock, but lets just say I’m either ripping them out or adding some 7" light bars this weekend. Tail lights, on the other hand, I have the truck model, so I tested a number of the different ovals, the Grote brand (most expensive, US made I believe). just leaps and bounds above the others. Front turn signals, I still haven’t totally figured out. Peterson, who made the OEM ones, has some LEDs that are the same size, just need to fiberglass in a spot and drill a new hole for the mount.
Tried the MM, worked great. Eventually got a programmer though because I wanted to change some other settings and how I used the turf/road switch. Once you have a programmer, you don’t need the MM. The programmer is really easy to use there are only like 20-something settings on the T2 and of those it’s an even smaller number that you probably mess with. I would put the programmer as the 2nd best upgrade after the LEDs.
The GE motors are pretty tough. What will kill them though is if you have a leaking shaft seal on the transmission and you start building up oil in the motor.
What ended up killing my GE motor was stupidity of the former owners. The previous operators (a UC bus transit department) had not used two wrenches (one on the jamb nut / one on the nut holding the lead) when taking the power leads off and twisted one of the lugs around. After I took it off a few times, just disturbing the lug caused the wire to snap.
Bought a new 7.5hp blue motor from R4F, I’m happy with it, plus with the same red paint job as yours, I now have a red nosed cauck with a big blue thing hanging below it.
Don’t have lithium batteries yet - well not the main ones anyway. Running a lithium 7th battery (4s lifepo4) in a modified version of @Old_Houseboater 's hack. If you’re curious, there’s a whole thread on my ̶e̶x̶t̶r̶e̶m̶e̶ ̶s̶t̶u̶p̶i̶d̶i̶t̶y̶ highly scientific experiments that Dave @Inwo came up with to make this pack add on work. Maybe someday I’ll go to full lithium, I dunno. I’ll figure it out in a few years.
I never had much luck with the stock Zivan charger. When it finally died, Dave hooked me up with a used SCO QuickCharge that was re-branded by R4F, and that thing is great, I love that thing - but it’s not the right charger for lithium. If you stay on lead batteries, totally worth it. SCO even has an 84v model, could do a 7th battery hack, get a shunt and an 84v charger and all 7 batteries charge at once. I might just do that in a few years.
Had to get new shocks for the front, not really any options there right now, bought them from NEV Accessories like everyone else, made the thing ride even more like a piledriver. Apparently the NEVA shocks use a stiffer spring than stock. Yay.
Oh, and brakes, yeah, the stock brakes on an 02 are just a chit sandwich. Had 2/3 of a pallet of kegs on the back once (about 800lbs) and needed to go from 30-ish to 0 in a hurry. The whole time I was wondering if I was going to stop before I crossed the county line…
