TVR Cerbera Heater Control ECU Terminations.

[p16kee]

Hi was wondering if anyone could, i remove my Heater control unit so it could be repaired and like a total tool I did not note which connector goes where i.e top or bottom as both the connectors are identical. i also dont know what way round the ribbon cable goes in. i have tried looking for drawings but found that the electrical drawings are not very clear. Could anyone help me by taking a picture of their Connector Blocks and ribbon cable going into the Heater Control ECU please as that would really help.

Its in the passenger footwell next to the ECU stuck to the top with velcro. (well, on my early 4.2 anyway)

I can get one this morning and will post it up.

You can get the correct orientation of the ribbon by the small holes in the connector.

Well done, you beat me to it.

Ok thanks for that my Heater control unit is above the passenger footwell, may thanks.

Hello,

I'm now trying to diagnose my absolutely non working ventilation... The ribbon cable seems damaged, and one of the pins of the panel was bent, leading me to think that the whole stuff has ben unplugged may have been plugged back improperly.

Do someone know how to plug the ribbon cable properly to the control panel?

Thanks a lot!

Hello again,

well,plugged the thing back and everything is working. So here is a picture of the right way to plug it. FYI, if you plug it the wrong side, it will do funny stuff, but won't burn (I tried it!)

I think there's a "1" on the black plastic connector that tallies with the 1 on the PCB.

I find the blue LED very dim compared to the red one, can't see it all all in daylight; can anyone suggest a suitable replacement?

Thank you for these photos

I removed both connectors without taking a photo first, then discovered they are both the same

Didn't want to risk getting it wrong and frying the control box, well worth searching for the right photos!

I'm surprised no one mentioned the burning marks on the connector for the thick black wire....

P.S. was N7GTX in a former life

Ah a small hint. Those plugs are just hot glued together in the box, which in my case meant that separated and the aircon was working/not working, as the plug moved, just enough to make/break connection. Very frustrating trying to find

I fitted proper PCB spacers on the boards, as there were none originally. They relied on the case gap/plugs to hold them
