[PSUBS-MAILIST] Kelly controllers

Thu May 19 08:53:56 EDT 2016

Alec,

I am pretty sure that is correct. The side thrusters are 14.5 amp 36V and I believe 1/3 horse and the rear thruster is 74 amp 36 volt and 3 horse. I may have to take them apart to look at the plates on them again. The problem I am having is the spike from on/off in either forward or reverse frequently pops the fuse. Is a motor controller the best way to fix this or is there a better way such as a capacitor? DC electrical motors and engineering are my two weak subjects in submarines. 

Thank you,
Scott Waters
