Default g2 restoration

if any of yall ever venture over to the electric yamaha section, you would see the thread i did on restoring a g1 electric cart. as a teaser ill show yall a before and after

before


after


anyways, traded it last night for this g2 gas powered cart and a shotgun lol. the g2 has some wiring issues, and im sure the carb is gummed up. but the motor spins over, just no fire to the plug. hopefully if its warm around here this weekend i can tear into it and get her fired up. needless to say, the plan is, new paint, classic golf cart white. new tires, redo the seat, not sure if im going to recover it myself like i did the last cart, or go with a new design. new top and just a few little touches to make it unique. advice is appreciated as this is my first gas cart.

Good start for a good cart! Check out http://www.buggiesgonewild.com/gas-y...-diagrams.html for wiring help.

What you do TO your cart depends on what you plan to do WITH it. Street? Carry your golf clubs? Cross country? Hunting? Show? The other two major variables to consider are your skills and your $$$$.

i already know what IM doing with MY cart. i was just simply asking for advice as far as common problems people have with g2's? and yes that wiring diagram is going to be my buddy for a while. lol. the nice thing is i have a full shop at my disposal. aka tig/mig welder, plasma, cnc mill, should get interesting lol. tonight i was thinking about a vinyl top. i think it would be kinda cool. and when i pulled it out of the back of my truck the top shattered . guess thats what happens to 20 yr old plastic when its 30 outside

was able to do some work today. looks like im going to need a new harness. not sure if this one can be salvaged. and my ignitor is toast. one of the male plugs broke off inside the plug. after looking up what a new one cost i think im going to try and hardwire it into the harness. im simply going to solder the matching color wires to the board itself. then put quick connects on the other ends of the wire. anyone ever tried to salvage the board?

stripped the cart down a little


ready for paint prep


broken plug


other side


matching wire donated from an old car harness i had around

fixed the ignitor box. actually turned out better than i expected. if anyone wants a write-up w/ pics on how to do it i can. but its pretty self explanatory. heres the pix of start, middle, and finish. hopefully by tuesday ill be able to see if this is the only problem with the cart.

Ready for solder


other side. drilled a small hole where the broken plug was


solder the joint


plug other wires in, tape and done, ready for hardwire

thanks for posting these pics! My ignitor box on my g2 filled with water and the two caps on the right corroded right off!I am gonna try and see if i can just re-solder new ones on and maybe add a couple jumpers too the traces if needed.if it dont work im gonna put a HEI ignition module off a 1978 chevy half ton on it and call it good.

Wow, cool repair and yes they are pricey. That thing actually idles at 0 degrees advance then ramps up to like 30 degrees at 2500rpm, the curve is in the manual. I've been wondering if I should try to make it work on my clone. The G2 version has a rev limit the G9 does not. I bet someone could figure out the circuit and disable the rev limit on the G2....

Well i can tell you i have figured out the HEI module will do just that and allow for a hotter spark fr better combustion.

I'd love to see how to wire up the HEI. I've got a G2 and better spark is always welcome.

Lot of people also use the old Ford ignition box to go electronic on projects. I don't know what ones have a curve in them, I know the early HEI still had advance weights in them.
