Hello. My name is XXXXX XXXXX I will be assisting you today.
Did this only start after you replaced the relay?
I have not replaced the relay only the glow plugs
Was it starting ok before you replaced the glowplugs?
no - it was very difficult to start and gave out a lot of smoke when it did finally start - also just a bit more info - I have disconnected the wiring to the glow plugs and it still happens
I would say you have either a faulty battery or a faulty starter motor or a bad earth lead.
I will check all this out if there is not a problem then how do I get back in touch?
Just come back to this page.
Because the volt drop only occurs when in the crank position means the glowplugs are not the cause.
It will be some time tomorrow will that be OK?
It has to be starter motor, battery, connections, earth lead or at worst a partially seized engine.
That is ok.
