All of what you say is true. Please correct me if I am wrong but I
don't think you would want to connect this meter to the starting motor
circuit. That does open the question of the best location to insert
the ammeter. I am ashamed to admit I have not looked at the wiring
from the standpoint of inserting the ammeter.

I'm sure some better informed sparky will correct me if the following
is
incorrect, but an ammeter will indicate the net difference of currents
in the
car electrics. Therefore your calculation below will be true only if
you are
parked up with the motor off. When driving the alternator will be
providing
juice back into the wires so the overall difference should never be
17A. This
is where an ammeter will be useful - if you see this sort of current
then you
should be preparing to push :(
The largest current draw that I can think of will be the starter
motor. I'm
sure that these meters will have some kind of overload protection in
for when
the motor is being cranked over, so I would be inclined to get the
30-0-30 type
as it will give a more visual indication for small variations in
current.

Hello all,
I was thinking of putting an ammeter in the Spit. What range should I
get? 30-0-30 or 60-0-60. What in that little car would pull more than
30 amps? One of the biggest loads I can think of would be the lights.
I would guess that the lights are 55 to 60 watts so lets assume 100
watts to be safe. 100/12*2=17 amps. What is the general experience
here?
TIA
