Ill second Iras suggestion to go to AeroElectrics at MatronicsBob Nuckolls is a
true guru for all things electrichas been very helpful to me w/ my
electrically-dependent
engine, particularly w/ regards to developing my plan B in the event
things go south while airbornehis book is a treasurehe does not, however,

PS: For the curious, I am focusing on getting my cooling system to do the job
