Subject: Sparky the TD, (longish)
Hi,
So I'm getting a handle on a problem with my '52, and I figure that now
is
as good as a time as any to throw another one that I was leaving on the
back-burner 'till the big one was sorted out.
Backstory:
TD came back to life after an almost year-long mechanical restoration.
Battery was replaced, generator and starter were re-built a year prior.
After a few days back on the road the battery dies. I consult a wiser
head
then mine, and he believes that the regulator may have stuck in the "on"
position, so I clean it up and it seems to do the trick, but four or
five
days later the battery dies again.
I happen to have a new regulator, but it's in a different location.
Before
I can replace it a core plug blows and I have to deal with it. In
dealing
with it I pull off the starter cable to give me better access to one of
the
manifold nuts.
I charge the battery
I put in the new regulator
The starter cable isn't hooked up yet.
I hook up the neg side of the battery, (it's a positive ground system)
I go to hook up the ground and SPARK!
To troubleshoot it I leave the ground disconnected, and then pull the
wires
going to the regulator. I then hook up the ground on the battery and
reconnect the wires to the regulator one by one.
When I get to the wire that runs to the back of the Ammeter: SPARK!
So I check the wiring on the Ammeter, and it is hooked up properly, nor
can
I find any exposed wires ruling out shorts.
Looking at the wiring diagram the other wire on the ammeter goes to the
starter switch which goes to the starter which is still disconnected.
So here's my questions:
1. Could the spark be due to the starter being unhooked?
No.
2. If not then any suggestions on where I should start looking would be
appreciated...
There would appear to be an internal short somewhere. Since it's not
blowing a fuse, there are only a few areas where there could be a short.
Off the top of my head, I would try the headlights, horn, maybe wiper,
and most parts of the ignition system. Look especially closely where a
wire enters or exits a component. Make sure the distributor points are
either open or disconnected, since if they are closed, you will draw a
(small) spark.
=================
3. I noticed that when I turned power on to the lights they didn't come
on.
Also I put the key in and turned it and I didn't hear the fuel pump
clickeing, so obviously the electrical system isn't working with the
ammeter
unhooked. Is this by design, or do I have another problem?
That is by design. Most all circuits except the starter go through the
ammeter before going to the various components.
=================
I'm not going to be back home until Friday, but I'd like to hit the
ground
running on this, so any help appreciated.
