I recently bid on a G1 from a government auction site. Got it home and it would not turn over. After checking out the wiring, found a 1 in by 2 in black delay box on right rear fender with power in but not out. Wired around this box and it started and ran like a new cart after I bypassed it. Found out from yamaha tech that this part is obsolete, no longer made, and not needed. ..steve

That's great news. What site may I ask? I scan the Gov. actions all the time.
 
I would like to know how you rewired it I have a bad cdi box also. Did it have 6 wires, I cant find one either?
 
I too would like to know how to re-wire this. I am having the same issue, and is the black box the very back one?
 
My G1 only had one small black box about 1 i/2 by 2 inch on passenger side back fender. It had 2 wires in and 2 out. I simply wired around it. My rear axle broke into 2 pieces last month. Local mechanic charged me 125.00 to take it apart and weld it back.. In the process I lost the double ended spring off my throttle cable. Does anyone know where I can find a replacement. Steve
 
He is talking about the delay box not the cdi box. The delay box is so the relays don't click on and off every time you step on and off the gas pedal. (one second delay)

The purpose of the delay is to extend the life of the solenoid (less arcing).

You can jump these by making a short jumper with a spade terminal at each end then plug them into the harness. I remember opposite corners (white wires need jumped I think).

If you get it wrong you can`t hurt anything. I remember doing a boatload of them.

CDI boxes rarely fail.
 
you can replace cdi with cheap cdi box off ebay just get wiring harness and rewire with 5 wire cdi box the 2 wires for pulsar can be
rewired with diodes toward coil and wont cost but about 15 dollars runs great better than 200 dollar replacement

You just wire 5 pin CDI box and use diodes to wire the one pulsar lead to the 2 pulsar leads off of the carts cdi wiring

I use the cheap ebay 5 pin box about 16 dollars with the wiring plug the box I uses has these wires on plug Black/white , blue/red, Blue/white, Brown/yellow, Green
On these cdi box it is as wired :
Blue/white ... pulsar coils
Brown/ yellow...spark coil
Green ....ground
Black/white......kill
Blue/red .......source coil

These are wired to your cart as follows this is from cart wiring to new 5 pin cdi box :
Black/ white to black/white
Brown to Blue /red
White/red thru diode to Blue /white
White/green thru diode to Blue /white
orange to Brown /yellow
Black to green and ground wires

use 2 in4004 diodes with stripe toward new cdi box use a diode on each wire, ( white/red, white/green) before it merges to the one
blue/ white of cdi box
