Early 90 headlights not working

Early 90 (glass fuses and relay behind binnacle )

Both high and low beam stopped working ,I've tried new switches

Low voltage (2-3 volts) at fuse box

Where should I be looking ?

Thanks

Clean the fuse holders
Check switch for 12v

I clean the fuse holders every few years when a problem crops up, usually helps.
Incidently almost every fuse was the wrong rating when my son bought it.

Once you've found the fault it's really worth 1. changing the fuse holder to std blade type fuses, and 2. re-wire from the light switch/stalk to 2no new relays, one for each headlight - this ensure low current switching and will save your light switch contacts from burning out.

Both upgrades are very easy to complete.

Thanks il check the fuses

Did you get your lights sorted?

Fuses are fine (checked with multimeter)
Low voltage at fuse box with fuses out just need to work out why
