Relays Hot
Not had time to look at this yet but thought I would post in case anyone had a similar experience.... I was running my Zetec engine for the first time
today and noticed that my fuel pump relay and fan relays were getting hot. They are well rated @ 40Amp so would not expect them to be hot. Anyone
experienced a similar thiing?

Relays do get hot or warm, you have an energised coil in there that is working all the time to maintain the electrical contact. Cheers Ray
To make a car go faster, just add lightness. Colin Chapman - OR - fit a bigger engine. Chippy

rough calculaiton shows that coil will consume 2 W of power; that is eqivalent to one or two instrument bulbs.
so getting warm is ok - depends on how warm though!

Might be worth checking the switched connections on the relay as any bad contact will soon heat them up.
Finally back on the job!
