To the OP, note that you will still need a flyback diode to protect the switch, even if you skip the ext contactor.
I am familiar with putting diodes on the battery master solenoid. If I decide to only use the internal solenoid on the Skytec 149-NL starter, where would I put the diode?
Also, I am picking up the internal solenoid will draw about 5 on the activation line??? This seems high as I thought the battery masters only had a draw of about 1 amp (I may be confusing transient current flow vs steady state?) Please keep the advice coming, I am limited on my EE skills.
