Continuously popping pop-up!

From CEM to VEM, from LED to lightbulb and more. If you have an electrical problem, like a broken info-centre, search for answers in this category. This is also the place to be when you expect the problem to be of an electrical nature...

Continuously popping pop-up!

Post by jamescarruthers » Tue Jul 24, 2018 4:07 pm

Well this is a new one on me! I've never had a pop up light problem with 8 480's until now!‎

When selected, the left pop up light comes up and stays up perfectly. When I go to retract the lights, the left one continuously goes up and down.‎

See video here: https://youtu.be/Kd6BFxcWA0k

Is there a microswitch that tells the circuit the light is UP that I need to check‎?

It is usually a sticking relay that causes mayhem. The tallest one in the relay compartment is the culprit, can't miss it.
Since you have two identical cars, you could swap them to see if the relay is faulty.
The relay itself can be refurbished, try opening it up and clean the relay contacts.

Phew! Yes, I can have a go at contact cleaning. There's probably corrosion on theterminals after all this time.

Thanks Brinkie
