When I picked up my 4200CC from Anglia Car Auctions at the start of November, it had had to be jump started. I also knew that it had been sitting around since flexwing sold it earlier in the year, and it still is believed to have a tracker fitted. Coupled with the fact it gets sporadic rather than daily use, I knew that drain was probably an issue and a new battery would soon be required. That day came recently when the car would not turn over and so I bought a new Bosch S5 096 yesterday.

I also suspect I have issues with a, as yet unidentified, leak into the cabin given the amount of condensation inside the car.

Went to fit the battery this morning and I can confirm that getting the old Exide battery out and getting the new Bosch in was simple in principle and trickier in practice because of the lack of clearance between the battery and the relay/fuse box just above. The Ctek connector that had been installed also got a little in the way of loosening the 10mm battery post clamps. However, all was successfully achieved.

Off the car, the old Exide battery only showed 10.5V on my multimeter so unsurprising that the car had failed to start.

I gave the new battery a good hour before turning the ignition on and leaving for approx 1 minute to allow for systems to calibrate. I then turned the key and eventually the engine started but no HVAC at all, no indicators and no washer wiper. Strangely the hazard lights were working so clearly no issue with the fuse for the lights and I was getting somewhat nervous about the lack of response to the column stalks.

After a quick once round the block, I turned off the car thinking I will just need to get the car to Voicey and hope it is not too expensive to sort out fearing relay or ECU issues.

I decided to try turning the car off and on again and to my relief, HVAC, indicators and wipers all started working again. My first experience of the famed Italian electrics.

Fingers crossed all will be fine come its MOT in 2 weeks' time by which time I hope Voicey will have cast his eye over the car. Still, the car has character.

You will probably find that this was caused by the ignition key not returning fully to its normal position after starting, mine did this, and took a while to work out why, as next time it was started was fine, I always check that key has returned to ignition position now as a matter of routine, (or I would if it was actually going, Lol) some wd40 sprayed into the ignition switch may help.

Tha battery bit of my tracker was behind the driver’s side rear quarter panel.

I’ve had two leaks on mine. Fuel filler and top corner where the bonnet, wing, bulkhead and scuttle meet.

The carpets don’t hold any water but the insulation underneath soaks everything up. It took me two weeks to dry it out after I’d removed it all.

Good luck.

Good luck, it's not silver is it, mine had similar problems, voicey told me to check the connections on the passenger side of the transmission tunnel, there's a panel that comes off but that didn't work

Hi there. Condensation? Might be the heater matrix, As you know that was one of the reasons the car was sold. Both 4200s I have owned had intermittant electrical issues. I suspect the ignition switch might be sticky as turning the switch off then on seemed to solve any problems I had.
Good luck! I still miss it though and secretly started looking at 3200s. A lot more reliable I hear!

Definitely worth bypassing the heater core if it is suspect, also check the front passenger side footwell for wet as there are loads of electrics under the carpet.
The matrix isn’t too bad to change and will give you chance to check everything else. Great guide on here.
