[Healeys] Tonight's Wiring Dilemma

[Michael MacLean]

 John,     Go back and re-read my email.  I stated that the wiring diagram in the original shop manual for the BN2 shows the exact same wiring as the color coded one I am using.  I frequently check the two against each other and have yet to find a difference.Mike M

I have not checked the circuit diagram that you use but you would better to use those in the workshop manual.  The BN1 version shows the wiring to two overdrive relays and the centrifugal switch and to the wiring to the overdrive. BN2 version has far less wiring. There are also differences between the two, around the flasher unit.

As you can see in the two photos I am trying to connect the overdrive relay to the wiring harness.  Tonight's problem is not with the color coding of the wires.  It is the markings on the relay.  I have included a shot of my wiring diagram to illustrate.  In the diagram the connections on the relay should be W1, W2, C1 and C2.  As you can see on the relay it is clearly marked W1, W2, C2 and C3.  I'm confused enough with trying to wire this car as it is.  Having mismarked components doesn't help.  Just so you know, the wiring diagram in the original service manual shows the same as my color coded diagram.  Wrong relay?  Maybe mistaken relay.  At first I thought so, but I have two overdrive relays and they are marked the same.  I have been buying parts over several years and have duplicated purchase during a sale not knowing I bought the same part even cheaper a few years before.  So who is wrong, the diagram (I doubt it) or the part?Mike MacLean
