This is B110 diagram. B210 uses same colors (at least for some years) although the placement may differ slightly.

B310 colors may be same or may differ. In any case make sure both wires are connected (Start wire is the resistor bypass wire).

The B310 wiring harness already has a bypass wire. I don't know the color, but for B210 it is Black with Red stripe. It can attach to coil + terminal or to ballast resistor.

Hi Guys

Can somebody post me a wiring diagram to sort out confusions ? do i need to supply a bypass wire to the ignition Coil + when i crank the engine(means from ignition start position) ?

thanks

Actually if the ballast is broken it would start but not stay running.

The solution is to wire it correctly. Start wire goes to coil + side, and Run wire goes to ballast resistor.

Takes no money to fix this problem. Just put the wires in the right places.

if your bypassing the ballast resistor and it starts,then it is probly the ballast resistor that's broken,try fitting a non resistor coil or replace the ballast resistor

Quote:that indicates a wiring problem.

Simple fix.

When you try cranking does the starter motor get hot and the positive battery cable to the starter? Could be a broken starter motor internally. Try a spare starter motor

Hi guys

i have a problem with starting my b310 1978,when cranking it doesn't start but have fuel and spark too,,i noticed when i
Connect Ignition ballast resister wires together it starts sometime, if not know
i have a new ignition coil wires condenser plugs and wires too ,what is the reason for it ? do i need a connection to the resister while turning my key to start, does b310 want it ?

thanks
