Hi all. This is just something to consider when changing the bulbs in the warning light cluster or more specifically the ignition warning light. I changed the bulbs recently but discovered a little later that the battery wasn't charging and the ignition light was staying on. The wire from the alternator to the ignition warning light requires enough current to start the alternator working as it is connected to the field coils. Once the alternator is working it generates its own power to operate and regulate the field coils. My problem was that the bulb I fitted was of a higher resistance than the old bulb which would restrict the current and produce a voltage drop of sorts. It measured about 30 ohms whilst the original is about 10. Anyway refitting an old bulb restored operation. I didn't suss this straightaway I had to research a few circuit diagrams and read about alternator theory! This may be obvious to some of you so this post is for those like me who usually create another problem when dealing with the first!

Having consulted an expert,the email of which was found on the FBHVC website, it would appear that the type of engine conversion I have was available before ten years after the end of production of the stag so an MOT will no longer be required. i found in the last few years that some garages do not really know how to deal with a classic car regarding MOT's and I was coming away with a string of advisories until I found a sensible garage where it passed for the last few years without any advisories. 

Thanks for all replies. I do not know how long ago the engine was changed. It seems from everybodys kind replies that the information available is a bit misleading. I don't mind getting an MOT but some garages do not know how to treat a classic car and I was always getting a string of advisory which is annoying. I found a garage recently that I have used in the last two years that tests quite a few classics and I have had mine tested there with no problems highlighted at all. I look after the car and do very little mileage so would consider taking it for an MOT but not necessarily every year. I would just like the position clarified beyond doubt.Thanks to everyone for taking the time to answer my question.  

Hello to everybody. I bought a Triumph Stag about 13 years ago and it was fitted with a Triumph 2500 tc engine. It has always (since I've had it) been tax exempt as a vehicle of historic interest. As the engine is not original does this mean I will still need to get an MOT? Thanks 

Thanks for all your replies. I managed to get the overdrive unit off just after this post. I was only going to replace the clutch but with the gearbox out decided to tackle some noisy bearings and oil leaks.(note to self; leave things alone in future)

Hello to all. I have removed gearbox from the car to replace the clutch. I am in the process of removing the j type overdrive from the gearbox but it doesnt seem to want to come off. should this just pull off after removing the bolts or is there some procedure to follow, All help and suggestions would be appreciated. Thanks.

Thanks for replying. Looks like a strip down job. It passed the mot today as well. Thanks all.

Hi all. May be a stupid question but I had my stag jacked up at the front and removed the caps on the front suspension under the bonnet. When turning the wheel on one side the castle nut turns and on the other it doesn't. What should happen? Thanks.
