Little progress here and there

There's been a little bit of progress here and there. I've connected the DC/DC converter to the 12 volt system and succesfully too. The little voltmeter that plugs into the cigarette lighter outlet now shows 13.5 volts when I have power on. The converter was drawing about an amp when just charging the auxiliary lead acid battery, but with all lights on the current draw jumped to about 5 A.

I've also mounted the Cycle Analyst display in the dashboard. It's blocking the view to the tachometer and fual gauge, but they're not working anyway. Also it blocks the bright out-of-gas light as well, which was rather intentional. It does not block the speedometer or any other useful signals though.

In addition to the Cycle Analyst you can see a red flip switch in front of the gear stick. It has two positions. Forward or "AJO" activates the main contactor (provided that the car is turned on using the original key) and lights the switch red, albeit dimly. Flip towards the rear of the car or "SEIS", the main contactor deactivates and the car will not move by it's own power. Should be pretty easy to do that even in an emergency. Also you can always switch to neutral by hand, which should be doable even without the clutch.

I was also looking into some heat. I dismantled a 1000 W 230 VAC cabin heater that I got for 9,99€, but unfortunately the PTC heating element inside didn't put out any useful amount of heat at 80 VDC. Also it was quite small and pushing all the air though that small element would have been less than ideal. I did figure out a place to put it in though. There's a pollen filter that's easily accessible that I think I might be able to adapt to hold whatever workable heating element I can get my hands on.
