ok so 93 corsa 1.5td
lights on at idle is fine, but when you have the lights on and rev it to 2k the lights/dashlights etc start to pulse. is it new alternator time or is there a regulator etc on these that can be looked at? it only does this when warm also.
cheers in advance

There's a voltage reg on the back of the clocks that's replaceable, but if it only does it when engine is warm then I doubt that's your problem...

Multimeter on the alternator and see what your getting. Should be 14.4v. Get someone to rev it up while your testing also. If its fine the look into what dragon said

Get on ebay. Derv alternators are dearer than petrol ones unfortunatly due to them having the vac pump built in
