To allow me to bond the main nose mesh in position, I removed the radiator from the car. It slides out through the bottom of the car. The scissor lift came in very handy for this work.

 

Before removing the radiator I measured the clearance gap at the back of the radiator. This was because the front mounted fan was bothering me, and I wanted to see if I could find a really slim fan to mount on the rear of the radiator within the room that I have.

 

The gap was 60mm, and I manage to find a nice 16” Spal puller fan with an overall depth of 52mm, so I bought one.

 

This week I have been busy mounting it onto the back of the radiator. Once mounted I refitted the rad and fan combo into the car. I am much happier with this set up now.


Fan mounting complete.

With the radiator back in position, I pushed on with fitting the heater. I had previously fitted the heater in the engine bay, then realised that this is an IVA fail as the heater must not pull contaminated/fumed air in.

 

So I checked clearance behind the dash and there is enough, so this is where it has ended up. On top of the tunnel.

I removed the windscreen and fitted the vent trims as well as the ducting under the scuttle

Then refitted the screen

Finally I plumbed in the heater

I have two bigger ducts that you can see are hanging loose at present, these will eventually throw some warmth into the footwells

That’s my nice rubber floor tiles 😉

No they are far louder than that

Dashboard wiring almost complete.

Resistors soldered in over the LED Alternator/Charge and Brake/Handbrake warning lamps. I insulated these after the photo was taken

I see you’ve taken up drinking Gary, I know wiring can be a challenge but you can do better than white spirits.

Are those 7.5 Ohm resistors Gary? If yes...are they going to see a full 12V, because if so, I don't expect they will last very long as they look to be about 1/2W rated.

 

If all the above is correct, they will (briefly) get very hot before going pop.

Yep, surely they need to be in series with the LED?

There’s a need to have a parallel load across an LED when used as an alternator charge indicator/bootstrap indicator, usually something around 5W worth will do, so a 27 Ohm would do, but would need to be rated at 5W continuous dissipation.

 

 

ETA Those LEDs do look as if they are probably already ballasted to work on 12V

I am still working on the dash electrics.

 

@corsechris I dismantled one of the LED warning lamps as it had a loose connection and they definitely don’t have ballasts fitted.

They could have a regulator on the chip too. I thought I saw what looked like “12V” on the body in one of the pictures.
