Have tried the neg of the battery onto the new earth bolt on the chassis leg and again made no difference.
I had an earth lead from the bellhousing to the chassis and also a jump lead from the starter to the body, also a good clean earth point from the battery to the body, doesn't seem to make any difference !
Have also tried this with the engine and box out and on the floor, earth from the battery direct onto one of the bellhousing bolts !
The only way i can get it to crank over at a half resonable speed is when i have my battery charger hooked up and use the boost feature on it !
