[6pack] starter or battery

[Mark Hooper]

Thanks to all for the diagnostic aids:

It appears that the battery is at fault. If I put a set of jumpers on
from the city car then the TR6 fires right up.

So, the battery would seem to have lost it's charge and is not charging.
Strangely it is not hot which often happens when a cell shorts out and
the charger is left on.

Just as well in most respects. Replacing a battery is simple compared to
the starter.

Cheers,

Mark

Mark,
I just went through this last week and here's what the List suggested I
test.

1. Turn on the lights and turn key to run position.  If the Lights go
out,
you've got a short either in the starter or the cabling. You can then
narrow
it down by removing the 3 big main wires off of the starter post and tie
them together with a bolt. Lights on again, key to run position and
check if
lights go off. If they don't your starter is bad. If they do, you've got
a
short in your cables.
2. Test all battery readings the starter end of the cables as opposed to
just putting your meter on the battery terminals.
3. check the voltage at the WR wire where it leaves the starter relay
for
the starter, while a helper holds the key to the start position.  If you
see
12v here, check again directly at the starter, both from the terminal
that
gets the WR wire to the starter housing, and from the end of the big
stud
that gets the battery cable to the housing.  If you still find 12v in
both
places, the starter/solenoid is bad.

In my case just doing step #1 isolated the problem to a short in the
starter. Plus the smoke coming out of the starter was a dead give-away.
Once
I got the starter out I clamped it in a vice and hooked a battery to it.
The
gear jumped but wouldn't spin.

Now that the nice warm weather is here my TR6 has suddenly decided to
give
me a headache.

I've got a problem either with battery or starter.

When I turn the key to start position I'm getting a loudish chattering
about
4-5 times a second. It sounds like a small jack-hammer under the bonnet.

Yesterday everything was fine as I started her up perfectly normally and
backed her out the garage for a wash. When time came to go, very little
at
all., just a clicking noise when I tried to start. I put the charger on
all
night and now the chattering is loud.

So I don't know whether the battery is toast, or the starter solenoid is
doing something well known.

Original 1972 starter on the car.
