Can anyone help me with the following problem.
If the motor of my car hot/warm is, I have the following startproblems.
The startmotor does his work normally, but the controllihgts on the dasboard
doesn't light up.
A beepsound is heard from the little speaker in near the rearbackmirror ,
and the motor doesn't turn on.
After several startattempts, the dasboardlights normally funtioned and the
motor turns on.
If the motor is cooled down, I have no startproblems.
Thx in advanced: Wiel

Mmm... let me get this straight... starter will crank all time... sometime
inside dash does not work... Only when engine is hot....

I would start out by replacing the ignition switch... because your interior
dash/electrical should come on regardless of engine temperature.

I would start out by examing your battery connections.

Thx for your input,
the problem is that when I start my car and the dashboard dashboardlights
doesn 't light up ( when the motor is hot) then the motor doesn't start
while the startmotor normally does his work.
When I try several times and see that the dasboardlights normally function,
then the motor does start.
I think that the problem is not the battery or the ignitionswitch .
Can You advise me further about this problem, I think thats is a electrical
problem, but I don't know where I have to start with resolvongthe problem,
greetings : Wil.

I was trying to tell you that you have electrical problem... electrical
problem can occur due to heat... alot of current pass through ignition
switch and it does heat up.

1. If the battery is old (say three year old), I would suggest to change it
first and clean the electrodes that you can eliminate the battery problem.

2. If the battery is not so old, you may need to check the battery's water
level and whether the electrodes' condition.

Just for your information: When the over charge cut off circuit doesn't work
properly, it may charge the battery to overheated and eventually kill the
battery.

Anyway try the battery first :)
