My bike is a 72 750, with an original electrical system, apart from a Boyer MicroPower ignition, and LED headlight and rear light.
Earlier this year, I fitted one of those cheap ebay digital voltmeters, just to keep an eye on things. It was reading up to about 15v in normal running with lights - high, but, I thought, probably OK.
A couple of weeks ago, the bike suddenly cut out, and I noticed that the voltmeter was showing low volts. Switched off the ignition while I considered my options. After a couple of minutes I switched the ignition back on, and was surprised to see voltage mid 12's, the bike started without a problem, and as revs increased, the voltage went up, but the ignition warning light did not go out. So my assumption was that the warning light assimilator had failed, momentarily shorting out while so doing. I disconnected the assimilator and have been using the bike since without a problem, but the voltage now reads up to about 16 volts, which is definitely too high.
My assumption now is that the zener was damaged when the assimilator failed (or maybe vice versa).
So I suppose I am now looking at a new rectifier regulator unit. Is there anything else that I should check first? Has anyone experience of the Areg unit sold by AO and Paul Goff? If there are any comments about my assumptions, I would welcome them.
Thanks in advance for any comments.
