Regulator

Post by kgnoble » Thu Apr 18, 2019 1:53 pm

Experienced advice please :-)

Having replaced the original Paris Rhone regulator with an ECAS solid state one as a matter of course, I discovered yesterday that the dashboard voltmeter indicated over charging, and sticking a meter on the battery I realised that it was charging at 18v!

I checked the wires and all seemed good. As I was booked in for an MOT type test as a preliminary to the full IVA, I needed it sorted. So I dusted off the old regulator, cleaned it up, attached it to the same connections as the modern one and lo, the charging rate settled at about 15v before dropping to just over 14v.

Question - do I replace the old regulator again and hope that the new one works properly, or do I simply leave the old regulator doing its job? Are there many 2cvs still on original regulators?

passed the MOT apart from headlight alignment - thank you for asking :-)

Yes that's the one that went bad. I now have a replacement from ECAS....but the old original (and electro mechanical) Dyane one seems to be working well. The car was up on the ramp for the MOT with the engine running for about one hour and seemed to be regulated well

The one from ECAS is specifically for the Dyane. Any ideas why?

Hi,
There is no relationship with the engineering running smooth and the regulator, the regulator is design to ajustable the battery charging from the alternator, around 13,8 v. Higher voltage will shorten battery's life, blow bulbs and in case of Electronic ignition probably be bun it. You will also fin out that that acid level will need to be toped up more often this is for acid batteries with New technologies I am not aware. .
I do not think there is any difference between Dyane and 2cv as long as they are on the same voltage

Keith, just a thought on your regulator overcharging problem. Maybe it was not earthing effectively on centre tag, that would give the reg a false reference voltage from which to control the alternator.

Thanks for that thought.

Yes, I put a separate earth straight to the battery to test, and the regulator still failed. So I think for the moment I will stay with the Dyane regulator - and keep the new replacement in the glove box :-)

Earths remain a problem for me elsewhere. The rear light fittings for the Burton are, well, light! They are not well built and I have had a problem before with the earth - and it seems to be back again in a slightly different form but affecting the rear indicator/brake light. I think I know what the problem is - just need to think about the (permanent) solution.

Anyway - thanks again for the input. (Non IVA) regulation seems to be working :-)

Best

Keith
