Me three... I also have that issue.
To me, it isn't a problem, it's a feature... if you see your engine getting
warm, turn the lights off and the temp goes down by 15 degrees!

A A Hi,
A A Sorry for not giving all specifics, here are the details;
A A Yes, my car is parked 9 months, used only 3 summer months per
year.
A A I do have battery switch, little screw-on contact breaker at
battery
A A ground terminal.
A A I also really like this solution as it not only keeps battery
charged
A A during storage but it is completely removable, so it gives
extra
A A "anti-theft" protection on a trip if car is left parked outside
A A overnight.
A A This summer I already drove few times before Dolomites trip,
mostly
A A short 1/2-1h drives each time.
A A I never experienced hard starting before, it happened first
time during
A A second refueling on first day.
A A We drove many mountain passes and car would start completely
normal,
A A cranking really fast for next, I guess, 3-5 times.
A A Then, after next refueling, again it cranked really slow, than
again no
A A problem at all during next 3 stops, and, than again really
slow/hard
A A start on top of mountain pass.....then no problem any longer
during
A A next two days (at least 10-20 more starts, both cold and hot).
A A I do not have ammeter as it got replaced with Oil temperature
gauge, so
A A can not comment on charging, but I guess this should be Ok
since
A A battery seems to keep good charge, even after long drives with
lights
A A on.
A A One strange problem I do have, but doubt it is related to this
starting
A A issue is voltage drop at the instrument panel when lights are
switched
A A on.
A A I first noticed how my water temperature would jump up about 15
degrees
A A the moment you switch on headlights.
A A I measured instruments supply voltage at the bottom fuse on
fuse panel
A A (with car not running) and it is 11.8v without headlights on,
dropping
A A to 11.3v with headlights on.
A A I will look further into this and make more measurements with
car
A A running and try to find out where the voltage drop comes from.
A A It is probably a good idea to install some fused relays next to
the
A A battery and run headlights trough those.
A A For starting issues I will first check all the big ground
connections
A A and see if it comes back again; if it does, will make sure to
have
A A voltmeter in the car to measure voltages at the battery and at
starter
A A during cranking.
A A All the best, Robert

isn't it
A A then true that you came to your car this week and turned the

A A the first time in a long while, and then experienced the
problem on the
A A first day, but not on the subsequent days?
A A If I have that correct (it's supposition based on things you

A A in months/years past), then the problem is likely an obvious
one--you
A A had a weak battery from sitting for a long time.A It was
strong enough

start when
A A hot.A But after driving for a few hours, your alternator was

A A Is that a true statement?
A A Was your ammeter deflected towards the 'charge' side on the

deflection less
A A now?
A A If I lined up all my guesses correctly, you don't really have a
