Triumph Herald Alternator Conversion (originally published in 2008)

So it begins, out with the old and in with the new(er)

Started with removing the dynamo (strangely enough:-))

Please note that the dynamo may foul the distributor.

Got around this by loosening it off and turning it away from the dynamo.

Be sure to mark the position of the dynamo before loosening so as not too put the timing too far out.

I put a small felt tip pen mark on an HT lead to line up with the LT lead of the distributor.

The dynamo was then removed.

Tried a few test fits of the altenator with the various parts of the existing dynamo bracket.

It would appear the best way to do this is to remove all the existing bolts etc (including the large one in the alternator and dynamo picture above) and replace them with two different size bolts and a large amount of washers to ensure all the pulleys line up.

The Herald fan belt will also now be too short, I’ll pick up an new one when I get the bolts.

I have purchased an alternator for the old girl, and will shortly be fitting it and converting to negative earth at the same time.

Got a very good deal on the alternator, eBay of course!

I’ll publish the trials and tribulations of the conversion here in the future.

It looks as if only the heater blower, tank sender, battery and ignition coil will need reversing during the process, I think???
