Battery/alternator light staying on, draining current - HELP

[SNT]

I have a problem that my garage is simply unable to resolve.

Following a change of alternator, the battery and heater lights stay on after the ignition is cut, leaving the current open and draining the battery. The problem is solved by flicking the wiper switch, which cuts the current.

I have seen several posts already on PH which suggest various remedies, including changing the alternator. This has been tried, twice, to no avail.

My garage says he's tried everything he could think of.

Can anybody give me any ideas of how to resolve this?

Thanks.

I'd guess at a TVR (but I've been known to be wrong on very rare occasions)

I guess you meant What model?

Sorry.

It is a 1999 Chimaera 400.

Thanks to anyone who can help.
