No power to coil
Posted: 06 Oct 2018, 20:08
UPDATE: if I give a direct power from the battery to the coil, the engine starts so it confirms my suspicions about a break in the power feed. However, I still have my original question about where the power to the coil for a CU engine comes from. Is it the same as the DG which was asked in a similar post?
Hi all, I have a problem of no spark with my 2.0 CU engine. The van did a 700 mile journey over a week and wouldn't start the day after I returned home.
I've done a number of checks but basically the coil king lead doesn't create a spark on cranking so I checked the coil over and I'm getting no reading on my hall sensor. My coil is an old green label bosch with a -ve (#1 terminal) connecting to the green wire and the +ve (#15 terminal) connected to three black wires. With the ignition turned in the on position, I would have expected one of these wires to be 12v?
The problem, I think, is that the coil is not receiving any power so it would follow that it can't create any. What I can't get to the bottom of is where the power for the coil actually comes from? The fusebox in the glove compartment doesn't suggest it comes from there but I am stumped. I heard the 12v may come from the electronic ignition module but I can't work that out. Does anyone know where the 12v supply for the coil comes from? I'm hoping if I rectify this it will start but it's not a quick fix like I hoped.
Thanks all
