[Mgs] Overdrive does not work when it is hot. Checking for an open circuit

[Richard Ewald]

If you don't have an ammeter don't sweat it. If the resistance has gone up due
to whatever both the amperage and voltage will go down as a result. You can do
a test called a voltage drop test to determine if a fault exists and where
exactly the fault lies. Much easier than using an ammeter.
I wrote a long reply for the Healey list about this which has been posted at
www.healey6.com in the technical section.
