Speedometer magnet(ism)

[Dan Willis]

Hi all,

In all my years around DeLoreans, I've not come across this one.
So, first question is; anyone know any cross references or how the inner workings of the speedo work?

Here's the issue. My speedo needle doth not move. The mileage increases (both barrels) so before anyone mentions it, it's not angle drive or cable related . To add, I have the speedo out and have spun it up with a drill and, nada.

The speedo itself is a metal cup/magnet affair. The cup is attached (with spring) to the needle. If I spin the cup, the needle moves.
The cable-end has the magnet on it. No matter how I spin that, it doesn't drag the cup around (but the mileage increases so I know it's doing something right).

The question is, before I start dismantling it and realise I can't buy a new one (really), is it likely I just need to remagnetise the magnet? That is, if I can. Otherwise, is there something else that should be in this that might be missing? (it really is just a cup and a metal rectangle that spins within it).

Cheers!

Thanks Chris; Google suggests there are dozens so I'll need to narrow that down a bit.

I've been referred to one in Glostershire somewhere, but between insured shipping and parts, I'm looking at "new" money ($€500) so I'm still looking in to options.
