Fault finding and repairing an old Bosch GSH 4 chipping hammer.

Thank you for becoming a member of my youtube channel.

I hope to post full videos to members.
This is an old Bosch GSH 4 Hammer. A very good hammer they where. Small, light, powerful and reliable.
The little brother to the GSH 11 E hammer.
They always had a common fault where the connectors of the field would break, but not this time.
eventually had to strip everything down to identify the problem as the speed controller.
luckily a second hand controller soon sorted it out.

What in the heck is the name of the gizmo you used to test the armature? Never seen that before, looks like something cooked up in the 60s
