Noel,=0A=0ASo before I got to testing the electrical connections, I cleane=
d every wire and connector. Sixty plus years of driving can create quite a=
 mess as you can imagine. I also noticed some of the wires we flattened ou=
t and look like they've gotten a bit hot. With all connectors exposed and =
cleaned, I drove the car down to the shop where I have a mechanic friend w=
ho helps me. On the way, I thought what the heck, let's give her a go. I t=
hrow the switch, hear a loud click and damn, the car goes in to overdrive.=
 It slips a bit of in and out, so I flip off the switch and then try it ag=
ain. This time it goes in and stays in. As I get to my mechanics' place, I=
 take it out of overdrive and discover my mechanic has closed up early and=
 gone home. So back on the road I try it again and sure enough, everything=
 works!=0ABefore I button everything up, I'm going to wrap some insulation=
 around the wires as what's there is pretty weak and since it's lying righ=
t on top of bare metal, why temp a flow away from where it should go and k=
eep all that current in the wires. I'm also going to double check the tigh=
tness and cleanliness of every connector, but I actually think this is goi=
ng to work! If it doesn't, I'll bridge the centrifugal switch as your mate=
s and you have done, but I'm hoping I've solved the problem.=0AWe'll see, =
but also the two o-rings is the way to go as I haven't leaked a drop from =
