Dead Water temp guage looking for water temp sender ?
I see three place for Senders for water temp guage
#1 on the Engine block (drivers side)
#2 on Water housing (passenger side)
#3 On water housing (on front of engine)
1) Which sender feeds the instrument temp guage?
2) Can I check to see if the problem is guage or sender by grounding the wire goiing to the sender ? (will the needle on the guage move?)
