[Healeys] overdrive problem

[Dave Porter]

Stumped is good in this case. Let's assume it was a faulty dash switch,
wouldn't be the first. Perhaps condensation in the relay and or throttle
switch? Did you hose/power wash the engine compartment prior to failure?

Hello, Healeyphiles -
 
This is a follow-up to my post of last week concerning my overdrive problem.
As alert list members will remember, my overdrive began disengaging
immediately as I turned off the dash switch and the problem persisted in
spite of two relays (original and new one) and the throttle switch checking
good.  Well, the throttle switch checked out as well as I could check it
without taking it apart but it's just a simple set of contacts and a cam to
operate them.
 
After letting out the Lucas smoke from the two wires to the dash switch
during a test drive, I found those two wires completely melted, along with
the plastic body of the switch.  No other damage that I could find.  Should
I admit that before this test drive I had removed my 20-amp fuse circuit
from the relay that would have protected those wires?  Long story, but I
did.  Sin in haste (to get the car ready for Southeastern), repent at
leisure.
I drove the car the thousand miles to Southeastern and back with the
overdrive electrics disconnected.  
 
All I have done since is to remanufacture the two melted wires and replace
them, running them from the switch along the wiring harness and out to the
relay, install a spare dash switch, and reconnect my 20-amp relay fuse.
Now, the overdrive and electrics are working as advertised.  I kept my hand
on the wires during the test drive and they stayed cool through numerous
overdrive cycles.  I'm still stumped.  
 
Happy Healeying!
