Sun Armature Tester

Note: These threads are old. I managed to restore these Sun Automotive Equipment threads from backups that I had made several years ago.
Hope you like them -

Here are a few pics I posted on GJ a few months ago. Finally finished the whole unit last night.

This is an AT1 armature tester, or "growler". The MOST interesting thing about this tester is that it uses a full-on 110v circuit to do continuity tests. I guess in those days safety standards were a little lax ;D;D

Those continuity probes are live 110v AC -- no recitfied DC current in this baby. WOW -- I can just imagine the fun that mechanics had "back in the day" with this little unit. On a bad day, you could kill yourself. ;D ;D

Looked like crap when I found it on e-bay







Look at those quality aluminum castings -- awesome!





Removed and rewired some dangerously frayed vintage cotton insulated wire --and installed a grounded plug
