Hello Gentlemen
As always racers i have a questions Recently changed the motor shunts on my group 12 motor, put new brushes on and put a 9 volt (the rectangle type) up to the braids for power and no go from the motor? Now is this because a 9 volt battery is not strong enough to turn the motor? The battery works on a falcon powered car but i gather thats because its very low powered.
Please advise gents.
A pleasure as always.
Robin
P.S Big Thanks to Stuart for lending me his F1 last week.

Hi Robin,
You right, a std 9v battery won't provide enough current to spin a Gp12. Group 12's typically draw over 3 amps ( and some well over that ).
See if you can find a good 6v battery with a higher amp rating as a cheap option for running motors up.
Cheers,
Phil.
Of course, you could buy a variable power supply which would solve the problem for ever!
You will have noticed more than a few in the box room on Club nights and your Club Shop can always get you one! (Ad!)
