Hi again..

I do apologies sincerely that I have only just been able to get back to you - unusually I was not on this last weekend.

With this issue that you describe - the alternator light coming on is indication of a charge circuit ( or related ) fault..

Given you have had work done in this area - ie, timing belt etc - it needs double checking because all of this - the alternator / drive belt etc will all have been off. So it needs to be checked for the wiring -for any bad connections on that circuit inc earth connections .. Too - the alternator drive belt... that tension / condition needs checking... Also too - and a common issue with these, the alternator itself. Some have a clutch arrangement ( on the pulley ) too on these on the alternator - that is a suspect also. All this needs physically checking out - again - given you have had work done there - all these will have been disturbed so there is every chance the fault you have / cause of, will be found there.

IF you still struggle after that - ie, you dont find the cause - then electrical tests need to be carried out when the light is determine exactly what is going on in that condition - that way you are sure to find it... but that will mean driving it to a garage while the light is on - rather than switching off / on to re boot it as you do... Unless you have test equipment yourself and can repair it yourself - in which case, at that time, I can talk you through.

Im very pleased to have helped you - Do let me know if you need anything more --
