Speedo "warning" lights - Not Working?
Gaston - February 17th, 2016 at 11:26 PM

Right.

So today, after driving the car around the block, I parked it at home for a bit before heading back out.

When ready to leave again, I turned the key, and the warning lights didn't turn on. I turned it a bit past that initial first "turn", and they turned on.

When heading back home, it happened again, and turning it a little past that "spot" didn't work. So I went to start the engine, without the lights (which I know is bad), and they jumped on as the motor started (didn't start fully though - I didn't let it). So I turned the engine off, turned the key again, and on they popped just as usual.

So any remedies in fixing my bugs little (or big) problem would be great. I take it that I'd start with the grounds, but have no idea where to look.

Thanks,
Gaston.

What year model?

It's probably your ignition switch is about to die.

It's a '71 S. Bug. And if it's any consolation, the horn also doesn't work, and I'm waiting for a part to fix that.

So you need to replace the plastic electrical contact part under the main ignition key

They deteriorate over the years and start cracking

I tried again this morning and the lights didn't come on, but the car did start (just made sure)

So I'll look into replacing the plastic electrical contact under the ignition key.

Oh, and also the turn signals and fuel gauge don't work, which I presume are also linked with the ignition.

Get some contact cleaner and check the fuses as well and make sure all the terminals are pushed on

I would clean the battery terminals, and then all terminals on the starter solenoid bolt and on the regulator. Eliminate all the electrical contact questions first, then have a look at the ignition switch. Strange things happen.
Cheers

Thanks for all your replies. I tried again around mid-day, and it worked by pushing the key a bit past the "on" point. At 8pm though, it is not working.

So I'll look into the grounds, as prescribed by bevoracing and vw54 (thanks for that), otherwise I will look into getting the ignition switch replaced.

Thanks for all your help so far.

Yup, clean all associated terminations for the dash light circuit. Disconnect the battery when doing this and try a small stiff bristle brass brush to make all the copper contacts a brighter shade of copper and not dull and a bit green.

Oh, and even take off and clean the terminals that come from the regulator B+ terminal, and depending on what year maybe clean those from the B+ back to the battery and even if it goes via the starter motor.

You're just trying to minimise any voltage drop from the battery to the dash lights.

If all that don't help then means the ign switch needs replacing.
