QuestionHi Jim.
Someone tried to steal my 1973 mk4 1300 spitfire at the
weekend. Among other things, they pulled off all of the
wires to the ignition switch. The problem I have is that I'm
not sure which one goes where, and the Haynes manual
doesn't help. There seem to be 5 wires (one of them a
double) and 6 terminals. Can you tell me how to reconnect
them? Any help would be greatly appreciated.
Thanks in advance
Marcus
AnswerMarcus,
Sorry to hear about the theft attempt.
Let me see if I can help with sorting the wiring back out.
From the Robert Bentley Manual for the MK III/MK IV &1500 (1968-1974) the right hand steer model for 1973 has 4 terminals. The Left Hand Steer Model Year 1973 has 6 connections in the diagram. Hopefully this will be close to your setup.
Remember that British Leyland seemed to change the wiring harnesses on a weekly basis, so this is only a good faith attempt at sorting the mess out.
The first color is primary color of the wire. A second color listed is the tracer color.
Conn # Wire Color Leading to
1 WR (White Red) Starter Solenoid trigger
2 N (Brown) Starter Solenoid battery lead
3 W (White) Coil lead, ignition warninglight
4 N (Brown) from #2,
5 WK (White pink) Radio power, Heater motor
6 NR (Brown red) Anti Run on valve
Having said all that (and hoping I still remember the correct power lead colors I'll also read off what is hard connected from the factory to an ignition switch from a '75 vintage Spitfire LHD:
1 White/red heavy guage wire
2 Brown heavy gauge wire
3 White medium guage wire
4 Brown small guage wire
5 White/pink heavy guage wire
6 Brown/red small guage wire
Ok, so at least the Bentley agrees with the later switch leads.
I'd offer to check on my '73 Mk IV/1500 out in the barn but it'd take several days to report back with an answer.
I hope this gets you back on the road again.
Cheers,
Jim
