Go to move the Vectra - except that battery is even flatter than a pancake and cant now get that one off the drive to get the elan out....
...ah, well - I'll park the VW away from any other Elans in the car park just in case you don't want to be associated..... leaving now

The electronic voltage regulator is built into the alternator. A failed voltage regulator is difficult to test, because the alternator will continue to put out 12 volts and fool the bench test equipment, but will not put out enough amperage to charge the battery when the car is driven.
The Isuzu symptoms of a failed voltage regulator are:
Seatbelt, brake, and battery warning lights on the dash all light up for no apparent reason.
Interior ventilation fan ceases working.
Engine cooling fan and air conditioner condenser fan cease working.
Car fails to restart after sitting. Ran fine when shut off, voltage may not have been reading 14 volts when running but 12 or a little more. Shows less than 10 volts when attempting to restart.
An important caution is that the Isuzu Impulse and Geo Storm have 75 amp alternators, and the Elan apparently has a 60 amp alternator, which is the same size as the 89 I-Mark RS (though no one has compared the two to verify they are the same). The case of the 75 amp alternator is larger than the 60 amp.
Another caution against purchasing a reconditioned alternator. Reconditioned means that they did not replace all of the parts within the case. Reconditioned means that they tested and measured and whatever was not obviously broken was left in and reassembled in the alternator. A bad voltage regulator is the most common cause of a bad alternator, and nearly impossible to diagnose with a bench tester. A reconditioned 75 amp alternator costs $52 and a new voltage regulator costs $68 (the rarer 60 amp alternator is more expensive). Reconditioned alternators do not come with new voltage regulators. They do not charge enough for a reconditioned alternator to cover the cost of the voltage regulator alone. So most of the reconditioned alternators have blown voltage regulators.
Additional concern: Most of the time when you exchange your core for a reconditioned/rebuilt/remanufactured item, they hand you a part that looks pretty abused, and though they may work, usually looks in much worse condition than the piece you are trading in as the core. It's surprising how many holes they can bust into the side of an alternator and still call it "usable".
The most prudent approach is to find a good alternator rebuild shop that you can trust, who is in your area, and have them rebuild your alternator and return that same alternator to you. Then if there is any problem, you can talk directly to the person who did the repair, and not a counter clerk at a parts store or the telephone operator at a mail order parts company.
that is a very helpful and informative post - I don't know how I missed it before....
....I would ask Phil, but he knows nowt about electrickery...and Pete only worked on Lotus stuff, not Vauxhall, so wouldn't have a clue either.... and I can't get hold of the poster of the information.
....I have no dash guage to rely on (but the altenator is fairly new - and if you think getting one out of an Elan is tricky, you should try a V6 Vectra )
Nah, it just hasn't been used for months and as it is due to go to the scrapyard (unless I find someone who wants a banger to drive to Gambia ) the battery is technically-termed as shagged.
