I do seem to find thing not right Ignition off - no power to red wire Ignition off - 13v at orange wire Ignition on - power drops to 1v at orange wire Tested with black probe on batt - and red at the fuse box or connector? Should I try black probe elsewhere? No smoke or smell when I’ve been testing Sent from my iPhone using Tapatalk |

Re: Erratic ignition now no power, no start
not trying to be rude but do you understand wiring schematics?

Re: Erratic ignition now no power, no start
iirc (it's been a while since I had a curvy). We had similar issues with the green connector/starter relay I think on the RHS under the black infill.

Re: Erratic ignition now no power, no start
then i would suggest that you take some time to understand the schematic a bit more.
it looks complicated but in reality its very easy. follow the coloured lines till you come to a connector/component then look at the connector/component for the route it takes through and out the other side. sometimes the colour of the wire changes so you need to follow that. if you have a coloured printer then print the diagram out. get a highlight pen and highlight the wiring you have done, also mark down voltages as you go with power on/off. start from the battery and work your way out. with fuses the power goes in one end (usually marked with the long line or no fuse at the junction) with things like switches there are dots/circles with a "bar" connecting them. this is to tell you when things are on/off and what way the voltage flows. as an example lets look at the ignition switch red wire. when the ignition switch is in the on position the red wire connects to the orange wire. when the ignition is off/lock then there is no power to anything, when the ignition is at park then the red connects to the brown. so if you put the red probe of your DMM in the orange wire exiting the ignition switch and the black probe on the battery negative terminal there should be no power on the orange wire when the switch is off, when you turn the switch to on then you should get 12-13vdc on the orange wire. if you get power where there should not be then disconnect the connector and probe the main loom (not the switch) orange wire with the red probe of your DMM. if you still get power then you have to probe deeper into the loom to find out exactly where you are getting the power from. its very very rare that you get reverse voltage and the most common is the battery being connected the wrong way round.. trust me i have seen people do it. or the negative system is shorting to a live. |

Re: Erratic ignition now no power, no start
ooohhh and remember that everything is "live" yes even negative (ground) will show voltage when a switch is switched on.

Re: Erratic ignition now no power, no start
Thank you all so much for you time and patience. I finally found the problem!!!
Something I should have checked ages ago going by the symptoms of no power to the fuse box. Anyone like to guess before I tell? Sent from my iPhone using Tapatalk |
