Radiator fan wiring - FYI
« on: March 27, 2016, 03:28:32 PM »
Lazy Easter Sunday morning,  consulting Da Google, looking for ideas to wire

up my Volvo two speed rad fan and came across the following link.  So far

the Volvo factory circuit and combo relay are in the lead,  but I may do a

circuit using standard SPDT relays for easier repair when on the road.



Mandatory Wedge content.....



Seems that the the dreaded  TR7  Parallel/series rad fan wiring circuit was

ahead of it's time.  The GM LS community has been using it all over the

world, this one from Oz...



See post #8

I'd use switch over relays in all three positions, but otherwise looks

pretty familiar...Nice simple explanation of how it works (see post # 16)

for those who are looking for that sort of thing...
