    Do you have a multimeter? When the engine is off the voltage should be between 12 and 13v depending on age/condition, when running you should see well over 13v over the battery, I’d guess this may not be the case if the light is on. Not sure on the PD130 but some alternators also have a smaller wire alongside the main positive which triggers the battery light.
