Hi All
Here's one for the electrical minded on the list. Car has been used on
a few short journeys and not had a chance to recharge the batteries,
started always first kick of the starter as it did last night. After
idling for a minute drove it for ten minutes and then stopped outside
house and looked at the battery meter on the dash.... It's jumping from
just over 12v to 15v rev the engine and it goes slightly higher then
drops again. Back to idle and its stable then starts to jump again???
What gives?? Alternator dying?? Batteries are 1 yr old and appear to
be charging well.
Also I am suffering the drowning but only when car is facing uphill.
Tried the hissing tank filler and makes no difference to my problem. I
am thinking of having the pump and fuel system overhauled while I get
the injectors serviced.
All the best

Sounds more like a bad connection than anything else. The condition or
charge state of the batteries would have no effect on the meter.

Also, try checking the connections on the back of the alternator, as
well as the straps on the batteries - check both ends where they
connect to the batteries/alternator and where they connect at the other
end.

Were your indicator lights on while you were looking at the battery
meter? I've experienced a similar thing, even when my batteries were
fully charged - if my indicator lights were on the battery meter would
jump up and down in rythm with the indicator lights.

I know what you mean but no I had nothing electrical running even the
radio was off. Went for a 140 mile run last night and the meter took
ages to indicate fully charged.
All the best

Do the dash lights, or the radio lights, flicker in sympathy with the
dash meter? Or better still if you attach a multimeter to the
electrical system (eg at cigarette lighter) do you see any variation?
If they do show variation it suggests a genuine problem: probably a
faulty diode or voltage regulator on the alternator, or possibly a loose
connection on the alternator.
If not I'd think either a blown voltage regulator on the dash
instrumentation circuit or a loose connection.
For what it's worth my tachometer sometimes behaves like this: jumping
around +/- 200 rpm or so at idle and showing a falsely high reading at
speed. And then just as mysteriously it tends to right itself for a few
days or weeks.

Mine too: park it facing uphill on a 1 in 1 slope and idle drops from
around 600 rpm to about 450. Not an everyday problem though!
If you do get the pump & injectors overhauled could you keep us informed
about where & how much? Having heard all the horror stories about what
happens when the injector spray pattern deteriorates, or the injector
leaks, I'm thinking that I should get mine serviced too.

Hi Guys
Can someone explain the process of charging to me.
I know the alternator charges the batteries and they are used to start the
cruiser but are they needed once the cruiser is running or is that the job
of the alternator to run all the electrics on the cruiser once running.
I was messing with head lights for a few days on and off while the cruiser
was switched off, but did not think this would have effected the batteries.
I ask because I started the cruiser this morning and drove 60 miles with
my lights on.
I stopped at a chipper as you do only to fing it would not start when I came
out.
It did start when jumped.
When running the voltage meter is where it always has been but when it would
not start the neddle was at the half way mark on the dial.
This would be a little lower than normal.
So if the meter is at the normal when running does this mean the alternator
is charging fine.
I did notice bulid up of the acid green stuff on the battery terminal and
washed this off with hot water.
Could this be the cause of the problem.
I also noticed I can disconnect the battery red terminal on the drivers side
battery only and the cruiser will still run.
If I disconnect the passenger side battery only would the cruiser still
run.
cheers

OK John,
Here we go.
The battery is used to start the vehicle and as a buffer when you
are pulling too much current for the alternator to provide. When you
run with nothig on then the alternator is fine, when your current use
exceeds tour alternator output you batteries are slowly getting
drained. This is most unusual. Your lights, if 4 headlights and
sidelights, would draw about 20 amps. That is well under your
alternators capacity. When your batteries get old their capacity
decreases and they do not keep the charge that you put in to them,
this can result in not starting in the morning when they have sat all
night. To not start almost immediatley the vehicle is turned off is
odd. This could be one or two things. The first is the connections on
the battery and the starter. Make sure they are clean and a good
contact, washing the corrosion off is not good enough as it is
probably between the terminal and the clamp. Take the terminals off,
clean them with a wire brush and put Vaseline on them before putting
them back. Clean and check the alternator to battery connection at the
alternator and check the alternator earth. Next we have your
alternator brushes. If you have not done it get a new set and fit
them, it is a simple job and well worth it. A simple check of the
batteries, one at a time, is to charge them and test the voltage
across them next day with a meter, anything over 12 volts should be OK
to start your car. Go through this and your problem will probably go
away, these are the most common faults with starting/charging
problems.
Regards, Clive.

Hey Clive
Thanks a million for that. Ill do what I can and see if it improves.
Im just a wee bit puzzeled because I had battery trouble last year and
bought two new batteries or at least that is what I was told.

John,
One thing I forgot, check your battery electrolyte regularly in
the summer months. Batteries do a lot less work in the summer, not
much use of lights and easier starting. They are still being charged
up however. This combination can lead to them starting to dry out,
which is bad.
Regards, Clive.
