Any one know how much current a starter solenoid will draw.

 

what starter what voltage [what kilowatt rating is the starter] need answers to these questions , anyone who says its bla bla bla without the info would be foolish

 

And why would the kilowatt rating of the starter motor effect the current drawn by the starter solenoid?
Personally I think it is foolish to not read the question properly
in answer to the OP, i guess you are rewiring and want to know what size wire to use? Measure the resistance of the solenoid, and do 12 divided by the resistance, then add a bit as a safety margin. This is assuming you are talking about a 12v system
At a wild guess I would say it will be less than 1 ohm resistance and pull about 20a, but measure your starter to be sure.
