Hi Listers,

     I was on a trip driving my TR3 that has a TR4 overdrive trans in it.
The OD had been working fine and then suddenly nothing would happen when I
threw the switch. I checked the relay with a test lamp and the C2 output
terminal (yellow/purple wire) lights up fine but the solenoid wouldn't
actuate. I tested the solenoid (Moss - aftermarket) on my workbench and it
seems to pull in fine. It probably only has 5,000 miles on it and looks
almost new. I put it back in the car and it doesn't actuate. I ran a new
wire straight from the C2 terminal on the relay to the installed solenoid
and it still doesn't actuate, although I can move the actuation lever by
hand. Evidently the solenoid is bad again. It seems like I go through OD
solenoids fairly regularly. Randall (does anyone know how he is doing???)
had me install a small "bounceback resistor" on the from the C2 output
terminal on the relay to ground to eliminate bounceback voltage spikes. Any
idea why I would be going through solenoids so regularly? I seem to change
them out about every 10,000 miles.

     Could it be a grounding issue for the solenoid? It seems like there
would be plenty of electrical continuity from the transmission to the engine
and chassis, so that shouldn't be it.

     Thanks in advance,

     -Bill Brewer

I recently went through FOUR aftermarket voltage regulators on a TR4.  They
came from different vendors and lasted anywhere from a few minutes to a few
weeks.  I sourced an original from Marv Gruber and it has worked fine ever
since.  What are the chances you could get your hands on a nice original
solenoid?

Randall Young is in a rehab hospital (Kindred hospital in Pasadena)
following a stroke.  I have spoken to him several times and encouraged him
to comply with the physical therapy as there were so many TRs waiting for
his advice!  It has been a bad year for him - his father died just a few
months ago.

<div class=3D"yiv6100358220MsoNormal">Hi Listers,</div>

<div class=3D"yiv6100358220MsoNormal">&nbsp;&nbsp;&nbsp;&nbsp; I was on a t=
rip driving my TR3 that has a TR4 overdrive trans in it. The OD had been wo=
rking fine and then suddenly nothing would happen when I threw the switch. =
I checked the relay with a test lamp and the C2 output terminal (yellow/pur=
ple wire) lights up fine but the solenoid wouldn=E2=80=99t actuate. I teste=
d the solenoid (Moss =E2=80=93 aftermarket) on my workbench and it seems to=
 pull in fine. It probably only has 5,000 miles on it and looks almost new.=
 I put it back in the car and it doesn=E2=80=99t actuate. I ran a new wire =
straight from the C2 terminal on the relay to the installed solenoid and it=
 still doesn=E2=80=99t actuate, although I can move the actuation lever by =
hand. Evidently the solenoid is bad again. It seems like I go through OD so=
lenoids fairly regularly. Randall (does anyone know how he is doing???) had=
 me install a small =E2=80=9Cbounceback resistor=E2=80=9D on the from the C=
2 output terminal on the relay to ground to eliminate bounceback voltage sp=
ikes. Any idea why I would be going through solenoids so regularly? I seem =
to change them out about every 10,000 miles.</div>

<div class=3D"yiv6100358220MsoNormal">&nbsp;&nbsp;&nbsp;&nbsp; Could it be =
a grounding issue for the solenoid? It seems like there would be plenty of =
electrical continuity from the transmission to the engine and chassis, so t=
hat shouldn=E2=80=99t be it.</div>

<div class=3D"yiv6100358220MsoNormal">&nbsp;&nbsp;&nbsp;&nbsp; Thanks in ad=
vance,</div>
