I am about to complete a three year ground up restoration of a 51TD. I am
have some trouble starting the rebuilt engine. Here is the situation: the
battery will not crank the engine, but it shows 12 volts and all the
accessories and the fuel pump runs; when I switch on the ignition, the
voltage drops to 7.5 volts; my new car battery will not crank the TD either;
however, when I jump start it (i.e., with the engine of the second car
running) the TD starts and runs fine.
What is wrong? Any ideas.
