Yesterday, after filling my gas tank on my 74 TR6, I tried to start the
engine, nothing
happened when I turned the key. I felt a loose wire under the dash. and
noticed it pulled
out of its solderless connector. I reached for my toolbox and quickly
recrimped the connector
with the wire inside. I tried the ignition again, still nothing, I removed
the back portion
of the ignition switch to find another loose connection, this one was a
thick brown wire that
seemed to go to either terminal 5 or 3. First I tried terminal 3. Turned the
ignition switch
nothing, then I tried terminal 5. The engine started. Twice while driving
home the engine
would start missing and die. but would restart. When I got home and tried
to turn the
ignition off the engine kept running. I finally popped the clutch with my
foot on the brake
to kill the engine. when I removed the back of the ignition switch it was
hot.
Looking at the rear section of the ignition switch I have the following
wiring
terminal wire
----------- ---------
1 White/Red - Thick
2 Brown/Red &
White/Brown
3 Brown - Thin
(empty connector)
5 Black - Thin
The rear section of the switch has the number 157SA (its Lucas)
My Bentley manual shows
terminal wire
---------- -------
1 white/red
2 (2) brown/red
3 (3) white
5 no connection
Should be looking for another loose wire, I'm supprised that I only have one
wire on terminal
3 and the manual shows three. (also I think I have a sports coil, because I
read an output
of 12V when the engine is running, Reading taken before this problem
happen. I replaced
the points with the Ignitor electronic ignition.)
Does the ignition ground out when the switch is in the off position?
I'll do more searching under the dash tonight. I wasn't able to do to much
last night.
Any help is greatly appreciated.
Thanks
