help warning lights

[shirley53]

I have just started up my truck and the warning lights eg battery, oil, t-belt etc remained on. Only when I accelerate do they go off, but when my foot is off the gas they come back on. Any help would be appreciated

Loose alternator belts (there are two) or the alternator is on the way out.

would the belts need replacing?. Hope its not the alternator as its just nearly a year since i replaced it .(second hand from Stormforce)

If the lights are still on when the belts are tensioned, then is the alternator thats faulty.
