Right then better start my '77 S1 project...


Recommended Posts

Great pictures all the best with the article.

 

Just had a thought on your charging problem. It is not beyond possibility that a recon alternator is giving a random fault.

 

Another thing that may help to identify your fault is to disconnect the battery. Connect the battery, positive first and see what kind of spark you get when connecting the earth. Anything more than the tinyest spark and you have a drain.

Bloody hell, easy when you know how! So I went ovwr to my local garage to get the alternator bench tested, they are ford specialist and great lads to boot. So I hand over the lump and they start a bench test, as it's on the bench on of the guys walks over and says, that looks like an rs3 alternator? He goes off and digs out a crusty old unit that they had laying about. The bench test was inconclusive on my alternator, so I said to the guys can I try that rs3 unit, just as a go, yeah no problem try it but we can't guarantee that it will work. So I bolt it on, down and dirty as a quick test and to my amazement the battery voltage starts climing immediately and the volt gauge jumps tp well over 13.5v! So a shitty old second hand ford rs3 alternator has come to my rescue. It fits with a couple of spacers so I'll be fitting this unit until it dies when I will replace it with another ford unit. Moral of the story don't buy cheap shit off of ebay, you live and learn.

I've just completed a clean and final install and looks like the readings are strong and healthy. I've just seen a reading well in the 14.5s so I'm pretty confident that this old and crusty second hand unit has saved the day. Just needed 3 washers to space it correctly inline. I'm so pissed off with my 'new' faulty unit I've just email the sod to try and get my money back! Test drive tomorrow, hopefully the sun's out, may even put the radio on!

I'm definitely at Shelsey Walsh, that's the biggest show in the retro calendar. As far as I know all 3 air ride lotus' will be there. Infact Rob mentioned a blast up the hill in his!

Yes mines going, and have the brakes in bits and new water pump install in progress so franticly trying to get it together and working! and yes plan to have a hoot up the hill if the brakes and cooling get sorted.........regardless it will be there even if its towed again!

The alternator you have there probably started life on an early eighties Fiesta. From memory they were produced by Magneto Marelli and pretty reliable as you have shown. I am surprised you had to add washers for alignment as it should have been a straight fit. I notice on the label it has 45 amp output which should be adequet for the Lotus. Did you compare the pulley size with your original?

loving the radio... the remote gives the game away though!

Hidden bluetooth headunit under the left dash (controlled by either that remote or better still my smartphone), my hunch is the original radio would still work if I could be bothered to get it fixed. There's also two 4" hidden speakers under the dash and two 6" rear speakers in the rear pods, it's a boomin' system when I want, trouble is I love listening to the exhaust note so it doesn't get much use!

  Awesome work, love the classic look but with the modern goodies hidden away,  Good call on the Oxfam jacket ;)

 

   Good work on the knobs also all these small details soon add up to a cracking car with a cracking interior.
