Wiring Route?

[jeffjohn]

I have connected an emergency solenoid connection via a relay to get around an occasional sticky ignition start problem. This works fine but the switch is in the engine compartment. I can't find a route through to the cabin. Does anyone know a neat route via redundant wiring already in place for accessories etc. My 1996 1.9 D xantia is the basic model so I am hoping there might be a pre-wired route! thanks

try running it through the rubber grommet on the accelerator/clutch where they go into the cabin.

many thanks techbod; that looks a good solution. I burned my in-line 10A fuse to the starter solenoid; what sort of current does it pull? jeffjohn

[techbod]

between 198 to 238 amps on cranking.

no no!! the solenoid - not the starter!

well I would assume it to be 12v which is all the battery can deliver and all the other bits are boosted like when cranking by amplifiers,

if the starter motor was getting harder to crank it could require more power and that could blow the fuse also poor earth connections.

I found an excellent site that shows the solenoid current as a function of time recorded on an oscilloscope; the peak solenoid current on the model tested was up to 28A; much higher than I anticipated. A wornout ignition switch was causing the applied solenoid voltage to fall below the "battery voltage-0.5v" range and the starter was not always engageing. I have since routed the switch voltage to a 40A relay, pulling only 40mA (12/320 ) through the switch and connecting the solenoid directly from the battery by 3-core 2.5 cable, protected by a 40A inline fuse. All starting problems now cured.
