Dash light problems

hi,

On behalf of a friend:

They have no generator light or oil pressure light on the dash. They have removed the spade conecter on both & earthed them out,,, yet still no warning light comes on.
Any ideas folk???

Cheers

 

Post a pic of the wiring. Could be anything.

 

Can't at the moment as I'm not there bud

 

Check the contacts on the bulbs

 

you have a friend ....

 

The bulbs are broken?

 

Art,,, I didn't even think.
I'll give you a call tom. When have you git a few free hours??? The van is in Brixworth

 

as snotty said, could be anything.

Most likely causes are:-

12V feed to the cluster is not live (black wire looping around instruments) either the wire has come off of the fuse box or the fuse has blown - is anything else not working?
No earth to instruments (although it usually earths via the screws if this happens
bulb holders not making contact correctly
bulbs blown
Wires to oil pressure switch and alternator making poor contact
oil pressure switch and alternator broken (unlikely)
