Anything over 18 Volts will generally cause some damage to the electronics

I am yet to see an alternator on an Omega capable of delivering more than 18V even with the reg shorted out.

Do check the fuses etc are ok as the supply current to the ancillaries will have been signiicantly higher under the fault conditions.

Unlikely (not impossible if its been badly designed or buggered with) as the fuse rating should such that it blows before the max I2T of the loom has been exceeded.
