Re: Voltage Regulator - H-Van Techni-Tacot reckon it'll be about 4 to 6 weeks before I can have the van back.
And mine's the slightly more economical HY-72: it was a good bit less than two tanks of petrol. But I wasn't driving very fast - my satnav reckoned an average speed of 50kph. Even with the noisy gearbox I could hear the radio playing most of the time.

Re: Voltage Regulator - H-Van Dennis wrote: I mentioned this in passing to Thierry Thomas who runs Techni-Tacot, and he knew immediately what the problem was. He said that 1-2-3 electronic ignition (which I have) doesn't like the power supply from a dynamo: it's sufficiently irregular to confuse the circuit board. In addition to doing the gearbox he'll fit an alternator (as found in later H-Vans).
This bit is speculation, but I'm guessing that the problem comes at least in part from the mechanical voltage regulator, with contacts that are either closed for charging or open when the battery voltage is OK. The electronic ignition doesn't mind the contacts being closed when the battery is charging (hence the first 30 km were OK), or when they are open nearly all the time (hence the remaining 500 km). What it doesn't like is the contacts opening and shutting rapidly.
Does that sound like it might be right? Yes. The good-old-mechanical charge relay doesn't fit with modern electronics. Same with 2cv and 123, some funny behavior may happen with that combination... The dynamo makes much more maky kind of electrical noise, what alternator doesn't. A simply electronic ignition may work with dynamo, but no 123, noise supression with its computer isn't designed to work with that noise...

Re: Voltage Regulator - H-Van My 2 Voltage Spikes. Try fitting a "Radio Suppressor" on the 12volt line to the 123 Ignition. See https://www.ebay.co.uk/bhp/radio-suppressor

Re: Voltage Regulator - H-Van Roger V wrote: Thanks Dennis, that quite useful information. Probably the moral her is, if your going to update, then update everything.  So, how is the gearbox. I'm just rebuilding a 2cv one after borrowing my sister's 2cv and having silent gearbox envy.  Again, my apologies for intruding with my H-van stuff. Techni-Tacot have removed the engine and gearbox in their impressive workshop down near Aix. They have done some work on the engine but I haven't heard exactly what (though I can see a new diaphragm on the fuel pump there, for example):  I haven't yet heard anything at all about the gearbox: so I am hoping that no news is good news. It all takes time.

Re: Voltage Regulator - H-Van The van had always been a camper, right from new. It was converted (by Currus) directly from the Citroen factory in 1964, so, unusually, the registration document shows it as a camper ("Carosserie: Caravane").
As a result in the last 55 years the engine hasn't accumulated a lot of kilometers, with use confined to a couple of trips a year: the dashboard says less than 90,000km (of which we did about 15,000km). So the engine isn't very worn. On the other hand, the gearbox had had long periods in a half-century of winters, when it was attacked by condensation and far too infrequent oil-changes, so it was leaky and noisy.
I'm hoping that it will all be a bit quieter after the rebuild.
