Fan wiring - bit odd

[FFMan]

I removed the radiator today as it had sprung a leak, and in doing so noticed the power feed to the fans has been altered.

It looks as if originally there were two seprate feeds to the fans, but someone has dropped one feed and made the connectors to power both from one feed.

I wondered if separate feeds were so that only 1 fan could be used if required, or is it to spread the load across more wires. Perhaps my redundant feed failed (I've not had a meter on it yet).

any advice appreciated.

Mine has two (pink) cables from the fuse board, one to each fan.
Bearly adequate, usual TVR wiring.

I believe that both single cable and twin cables to the fans are commonplace.

Some cars had a single cable protected by a single 40Amp fuse. Others, twin cables protected by a pair of 25 Amp fuses.

I believe the two cable/fuse method was adopted due to the single fuse blowing frequently due to the starting surge from the fans.

Have a look in your fuse box and see if you have two or single fuses.

Early cars had a single fan, which was subsequently upgraded to twin fans on many cars.... so it would not be a surprise that the wiring is a bit Heath Robinson

If your car is an early pre cat, this is what i found.

interesting - i think a rewire is on the cards - wiring looks a bit marginal though its never been an issue (yet).
