Hi all,

Helping @mattgreenworks by looking at the various ECU's. Posting some findings to this thread to maybe help future restorers.



He kindly included some sweets.

First module to look at is the ignition ecu


It doesn't look too bad from this side. Interesting to note the hand written label on the PIC16. I wonder if this chip can be read?

The underside of the board looks a little mucky and someone has been there with a soldering iron


The board seems to function correctly, but I've not tried to load the outputs.

A question to the community: what size are the terminals and is it possible to by slide on connectors for testing purposes?

I'm quite tempted to reverse engineer this board and produce a schematic - unless there is one already?

Cheers
Mark

Hi Mark and welcome to the TVR Cerbera control box club thumbup

I test(ed) all of my boxes with a 240V -> 12V arcade PSU and the terminal connections for applying the power can be connected using mini female crimp connectors as the picture below shows

If you need any hand with these boxes or their functions etc. just shout - between Imran and I, I think we have pulled all of them apart at some point and spent time getting them working again

For the PIC, unluckily no they are encrypted so can't be read with an EPROM reader - I tried and you just get unusable stuff - Paul who repairs these has the original source code but can't share it due to an NDA or similar with TVR

HTH

Test PSU



Power and negative connectors



Mini female blade connectors - I use shielded ones as the pins are quite close together on the control boxes and widen the connector a little bit with a mini screwdriver blade

I have no clue who could have tried to re solder all the joints .. not a clue at all ......
