Alternator?

[Mark Atkin-Barrett]

Last night the battery light came on and all the power was slowly draining from my car i.e. the windscreen wipers hardly moved, the indicators and horn stopped working...basically every thing that was electric either stopped working or had reduced power!!!

The problem got worse as i continued my journey.

I drive a Peugeot 106, 1.5 diesel.

As my battery is reasonably new (and this was happening whilst moving) i take it that my alternator needs replacing?

Thanks in Advance

Mark

Sounds like a major alternator fault or an earth fault.

More like an alternator, bear in mind a diesel does not need power to function, unless you have a fancy TDI with electronic injector system. (You don't)

Get the alternator tested.

Not completely correct as the stop solenoid requires power all the time to keep things going. Don't know how far the volts need to drop till it closes though.

Get the alternator tested.

Most likely is that the brushes have worn out. A cheap fix if this is the case.

check all wiring first b4 alternator though
as some further up said rightly,check the earth
also check that the live supply is good to the alternator,if in doubt temp run a wire to the alt from the battery and retest your charge rate with a voltmeter

I must confess to learning about diesels on tractors, so I am not familiar with stop solenoids, but don't they require voltage to activate open and closed, I think once they are open they do not require voltage until you again turn off the engine. Tractors have a lever that you pull to stop the engine, you can turn the key off and walk away leaving the engine running.

Being held open all of the time with electric sounds dodgy,surely it would burn out in a very short space of time?

again, I am not questioning your knowledge, this is just the way I thought they worked.

you've lost me
how did we get onto stop solenoids(which do need power to work its when power is cut off that they stop) but bear in mind that once working they dont req as much current to maintain the field
