relay testing

[swedge]

my fuel pump isnt getting any power, anyone know how to test a relay?

I also could do to know this! i guess you could just feed a live to it or the pump to find out?

[MK999]

it should click, if it doesn't click it's most likely broken/dead/MIA, there really isnt much more that can go wrong with them.

yeh just crank it over and put your ear to it. and if it clicking then just put a battery to the pump and see if its spinning,

ive got the car running using as spare battery to the pump so i know the pump is fine

ill have a listen to the relay

[auzzy-b]

Do you have it directly to the pump because the fuse may have gone! have you checked? other than that id say its bust but there only about £10 delivered for a new one:thumb:

[swedge]

the relay i wired in correctly through the loom, i was just stating i can get the pump running using a direct fdeed from a battery

[auzzy-b]

thats what i meant is your live wired directly to your pump? it could just be your fuse has gone between your pump & relay?

[swedge]

the wire that goes to the pump comes from the 9 pin plug from the c14se loom

i have converted from a 1.0

[auzzy-b]

Yea so its obviously your relay then:)

every nova owner needs one of these, laser tools do them, i've seen them on the net for a fiver plus postage. they will help solve all nova electrical woes, if you don't have one, get it on your pressie list

Or at least one of those screwdrivers with a blub in.
One of my most used tools at work, just because i cba to get my multimeter out.

but a test light can't tell you the voltage, it can just tell you that there is some current there

[Guderian]

Yeah those little jo-jo multimeters are very cheap, but i haven't managed to blow mine up yet, despite having used the 10 amp range on several occasions. The DC volts are drifting a little bit after years and years of usage, 2% high.

With relays, if they are the standard 4 pin with terminals: '30 87 86 85' you can most easily test them by substitution. They come apart with a bit of persuasion but you won't necessarily see much apart from the points 'throwing'.
