Using good old deduction I believe I have narrowed down my problem, but a s=
olution still eludes me. I have had earlier postings about electrical prob=
lems and many, many incorrect assumtions on my part. I have finally listen=
ed and worked on eliminating systems. I found that I was getting a 1.5 amp=
draw on the battery with no fuseable equipment connected. I disconnected =
the alternator and the draw went away. I wanted to prove what the problem =
was so I performed the following experiment.
Here is my test that in included 4 alternators and one known good battery. =
I constructed the circuit with only the battery and the alternator on a be=
nch. I ran the ground to the alternator chassis and put my multimeter, set=
to measure current, between the postive battery post and the alternator po=
st. I tested with the exciter wire on and off of ground as I was not sure =
about the proper testing conditions.
The first three alternators have been tried in the car previously. The las=
t one was in another car and was used as a baseline for sanity. A showed 1=
.5 amp draw; B and C showed 4 amps. Fearing that I was going insane and th=
at I was doing something wrong I tested D and that it showed .30 amps. So =
one would think that I have found my problem, but it still bothers me that =
this problem has shown in 3 seperate alternators. One of them is a new reb=
I guess what I am looking for someone to tell me why this test isn't showin=
g me the right thing or that it is possible to have this many bad alternato=
rs. If they are just bad, then is there anything in the car that could be =
causing them to go bad before I go sticking more alternators into the car a=
nd potentially ruining them. When I first started all of this the wiring w=
as not in the greatest shape, but I have tried to clean up all of the groun=
d straps and wires I could find.
Thank you once again and please help me to get this thing out of Ben's yard=
. Besides I have owned this car for 6 months now and I have yet to be able=
to drive it.
