any idea what these are? do? or fit?

I have these two "modules" currently sitting behind the afm, electrically connected but not mechanically fixed. Does anyone know what the purpose is and where they are fixed.

Cheers Shaun

They look like ballast resistors.

Could be in circuit to drop the voltage from 12v to 7v for the coil. There should be a bypass for when the engine is actually cranking on the starter but normal running would be through the resistor.

Another possibility would be ballast for the heater fan. TVR weren't quite so bad as this so it looks as though they could be fitted after-market or by an owner/repairer.

I'm sure there for voltage drop, for the lower setting for the dash and center console lights

Yep - certainly on the V8S they give you a dim and dimmer setting!

Sure are, Shaun YHM linking to a previous thread

They are deffo Ballast Resistors used to lower volatge from one component to another often getting quite hot in the process which means thay should be kept where there is access to cooler air when the car is being used.

i thought that they where for the dim/dip system on the head lights.

Cheers guys,

I thought they were resistors but any idea what they are physically mounted to?

I think they was just clamped to one of the chassis tubes.

Ah they go on the chassis in the engine bay, just behind the L/H spring housing/below were the body meets, there is a studs welded there and a 12mm nylok nut.

There is me thinking they were for the heater blower.

I can confirm that are for the dim (err... second off setting) on the dash panel lights. Took me ages to figure out what they where supposed to do, mainly because they where both so badly corroded and didn't actually do anything, they where quickly installed in the bin.

The DIM dip is a square black lucas box with 6 terminals velcro'd to the carpet somewhere near the fusebox, on my car it's functinality was about the same as the panel light resistors and it's fate identical.

I'm not sure why they did not use a potential divider, and have a varying brightness like on most cars.
