'87 spider starter woes

[TOMCCC@domain.elided]

I have an 87 starter that quit working about 9 months ago. I took it to a 
local rebuilder who rebuilt it. The first time I installed it, no start. I 
took it back and they "tested it in the back" and said nothing was wrong but 
it worked fine when reinstalled.

Last week, the starter quit again.  I took it back and the rebuilders said it 
was grinding slightly. $85 later I supposedly have a rebuiIt (again) starter. 
I tested the lead from the switch and I've got 12+ volts. The starter will 
engage and start with a hot wire from the battery but not from the ignition 
switch. Is it possible that the solenoid installed during the rebuild 
requires too much amperage.?

Help!
