70 S2 0044Q

Wish I was closer to you. This electrical s#÷t is beyond my understanding. I think I will have to bite the bullet and farm it out.

[Sandyman]

Sorry for the last rant. Not being able to comprehend the wiring diagram is frustrating.

[Sandyman]

Posidrive fail. Had to pry out with screwdriver replaced screws with Philips.

[Sandyman]

Where do I look for the cause of "power on" all the time? White wire going into right side engine bay relay is always on. It seems to me that there is a fault causing the power going to the #2 white wires on the Ignition switch to be on all the time. Simple to understand help very welcome. I am using the S2 wiring Diagram Prior to 700103000. Also looking at S1b for 2 fuse block and Federal for front turn signal / running lights.

I would start at the ignition switch.  Disconnect the NW wire and see if there is still power on the W wire.

[jbcollier]

If there is, go to the fuse box and see if the connections are amiss there.  On some fuse boxes, two of the fuses have a bridge between them (MGB type).  TR6 type do not have the bridge.

[Sandyman]

I now think that the PO miswired the fuse block. I can't make heads or tails from the wiring diagram. What should go where? The 2 upper left wires are brown.

[RoddyMac]

That brown wire on the lower fuse shouldn't be there.   White is ignition and should only see power when the ignition switch is on.   Brown is live all the time,  hence why the top is brown on one side and purple the other (horn is purple).  It should be white on one side of the lower fuse and green on the other side.  Green runs nearly everything,  wipers, signals,  gauges,  brake lights,  heater etc.   

[Sandyman]

Thanks Roddy, so all brown to purple, white to green?

[RoddyMac]

Yes.  No brown on the green fuse, white only.  And brown only on the purple fuse.

[jbcollier]

Check under the tape on the white wires and make sure any splice is properly soldered.  Then seal it with heat shrink.

[jbcollier]

You could also easily fit an MGB fuse box and then you would have four fuses.

Great day with rebuild. 95% of the electrics working. Turn signal lights wired in but no joy. Still trying to sort heater fan, full power all the time. When I put the heater fan switch to the bottom position the rad fan turns on. New fuel tank arrived today. Only one fuel outlet, no return line inlet. I am thinking of teeing the return line into the low pressure side of the fuel pump so as not to over pressure the carb. Thoughts?

That sounds normal.  First position = heater fan, second position = heater fan & rad fan.

How many wires come out of your heater fan motor?

Is this a federal car?  Does it have an emergency flasher switch?

[Sandyman]

John, my Europa is a 70 nonfederal export car. There is a hazard switch but no wires to feed it on the harness. The wiring diagram from this site for an S2 has 3 wires plus ground going into the turn signal flasher unit, mine only has 2 wires plus ground. The original  blower fan had a cooked armature and is scrap. the replacement fan is a squirrel  cage with power and ground wires.
