Spent a bit of time on the Indy over the bank holiday weekend. I was given an alternator with the kit, which may be off a VW Polo. It’s a 55amp unit which should be enough for the car for now at least. However it was covered in thick black engine oil, so I stripped it down and gave it a bit of a clean. Looks to be OK inside apart from the brushes which have seen a lot of action. I plan to run a small PC in the car on an off in the future so once I get this far I may have to replace this unit but until then it will do.
