[TR] Overdrive solenoid

[terryrs at comcast.net]

Hello, everyone.  Having fried a solenoid once, I thought I'd be smart--uhm, just shows how smart I am--and put an inline fuse between the OD switch and the solenoid.  Started with a 5 amp fuse, which seemed to be fine, but then started popping somewhat regularly.  So I switched to a 10 amp fuse, and that pops fairly regularly too, and increasingly.  Replaced the fuse 3 times in the past three days.  It happens while the OD is engaged.  

So, anybody know offhand how many amps the solenoid draws, including any spikes?  I imagine I'm saving the solenoid with all this, but then maybe it's the solenoid telling me it wants to self-destruct.

Thank you,everyone.
