speedo problem

Hi guys have fitted a new speedo to my 1971 vw beetle everything is working except the gen light and oil light . both were working on the old speedo be fore the change also when car started the indicator light glows dimly all the time .i have checked and don't seem to have any wires that i have missed .pictures of speedo attached any help would be greatfull

i would be checking the earth (brown wire)

There is no earth on the generator or oil light.

Check for power on the black + from the ignition switch. This is common to both lights.

isnt the speedo earthed somehow?

L bugs were different from memory

Generator light is earthed through the generator and the oil light is earthed through the oil pressure switch.

The earth on the speedo is for the high beam light, the fuel gauge and the illumination only.

The wire right at the bottom is live when the ignition is turned On...
pull the terminal on & off a few times to clean the terminals...
The Oil light earths out from the oil pressure sender on the engine...
[the oil sender is the small sender] You may need a new oil sender,,
If You have an alternator, the light Must go ON with the ignition.. and then off after You start the engine..... [alternator charging]
Do You have a generator or an Alternator...???
That is an alternator on My engine...
Generator's are smaller in diameter...


Oil sender is below the distributor...
if You take the wire off the oil sender and earth it to the engine - bare metal.. with the ignition turned ON.. the oil light should go on...
means You need a new oil sender...

the rheostat isn't turned all the way down is it.

Indicator earths via the flasher relay IIRC.
