[TR] TR4 switch

[Alex & Janet Thomson]

Sounds like that's your problem right there. You should have full battery
voltage coming into the ignition switch. Remember, the battery ground
circuit is just as important as the battery insulated circuit. Make sure
that ground straps that connect the body to the engine/battery are in good
shape. Under a load, each complete circuit (insulated and ground) should not
have more than 0.2 to 0.4 volt drop from the battery post to its final
destination.

I have found that the voltage to the switch is about 7.5.  is that right?
(the generator has been replaced with an alternator and it has a digital
voltage regulator if that matters)

 

And when I jump the connection to the starter nothing happens, so clearly
there is a problem with that
