I have a ford ka collection1.3i 2005 and if I have the heater blower on and say the lights or any other electrics on theres a pulsing and the lights flash and blower goes on and off also it drains the power from the engine causing jerking ONLY WHEN ACCLERATING ,just wondering if anyone could give me advice or suggest a fix , thanks gavin.

A common falt was the 3 wired plug on the altanator corrodes or wires snap off but still look attached,give them a pull,or have engine running all electrics on and wiggle wires see if this makes a difference,

check your charging rate and also would get your battery tested also,make sure your main leads/earths are sound also
