Installing 1990s type Tommy Gate - I need some help

I recently bought a model 64 TommyGate
off Ebay. The thing is in wonderful
cosmetic condition for a lift made in
the early 1990s.

My problem is that the lift didn't come
with the original manuals and the
downloadable manuals are for more
current models. For instance, the
controls on mine have just "Up" and
"Down" switches and no LEDs or "On/Off"
switches.

I need to know what the wiring diagram
is for this older model so that I can
get things hooked up properly.

Does anybody have an owners manual for
this type TommyGate who might be willing
to let me know where a couple of the
wires go and what the switch sequence is?

Thanks.

Rick,
Mine has the LEDs & one toggle switch,
I dont know if this is the same as yours, But if it is, LMK what you
want to see & I might can help you out .

Take Care
Pin-Del,
PS, I hate using mine, Safety Switchs or not !!!, Still caint believe I
got a finger caught in one !!

Mine looks like this:

I believe that the newer models have
their safety features integrated into
the external switch box. I think the
only safety mechanism on my older model
is a remote "in cab" switch that
provides/cuts the power to the external
switch box.

What I'm really trying to determine is
if my lift is supposed to have a
dedicated grounding cable that would run
from the pump motor to the negative side
of the truck battery. The lift came
with the cable that runs from the
positive side of the battery to the pump
motor but no other cable. The wiring
diagram for the newer TommyGate shows
the dedicated grounding cable.

Also, I don't know if I have to do
anything other than push "up" or "down"
to get this thing to operate. The newer
ones you have to press the "TommyGate"
logo on the switch box face in order to
activate the "up" and "down" buttons.
Actually, on the newer ones I think you
also have to put your left leg in and do
the Hokey Pokey before the thing will
operate. ;-)

For your application, you do not need a dedicated
ground cable. I would suggest you add a 4 guage
cable from the battery down to the frame just to be
sure you have a good ground. Near the battery and
straight down would be fine.

Rick I never installed one of these. But I really dont see it being
very hard. I was a car audio installer for about 13 years. Did it
professionally and I know a shitload about 12v dc type of wiring.

You wanted to know about the ground. What size wire is it using? I
would just ground the electric motor to the frame. Using a good ring
terminal and a star washer. I would then in turn re ground the exisitng
battery to the frame in the front. I dont care how thick of a wire you
run to the battery it isnt gonna be more conductive than the vehicle
frame. Also I strongly suggest using a circuit breaker within 6 to 18
inches of the battery. If that thick positive wire you run ever touches
the frame, its gonna be smokey time. It will burn that wire and
anything next to it. Also run the wire you run through some sort of
electrical conduit. Look at see what the maxium amperage the electric
motor uses and then use a circuit breaker under the hood. These are
available from car audio store all over the place. My cost on them were
about 18 bucks, and they are available from 20a-300a. Good luck

Thanks Fred. Will do. The battery in
my truck is one of those that has two
lugs for each pole so I'll use the
second negative lug to ground it to the
frame.

Damn, that's one I never used. I got to skip that generation somehow.

I'd be surprised if that was the only safety feature. Reason I say that is
that the generation before what you have pictured had a big knob that came
up from the lower part of the gate that you pulled up to make the gate go
down, and pushed down to make the gate go up (go figure). While you could
always pull it up to get the gate to go down, before you could make it go
up you had to flip a small lever around at the bottom that "engaged" the up
direction. Once you released making it go up it fell out of the way again
so you couldn't "accidentally" hit the knob to make it go up.

Now, there's the chance that since they moved the switches to the side like
this that for a while they didn't think they needed a safety mechanism. I
doubt it, though.

Don't know why you'd need a grounding cable. The thing is a big steel
object that's bolted directly to the best ground you have on a truck, the
frame. Your pump probably derives its ground from the mounts, just like
lights and other automotive accessories do.

Yeah, that's the generation I've dealt with with external controls. But
that generation has a little LED and must have some sort of internal PCB
with circuitry on it. Looks like you can remove your control panel and
look and see if there's anything complex in there, or if you just have
momentary switches that are wired to relays somewhere in the gate (the
relays are probably near the pump). If there's no advanced looking
circuitry then you probably don't have additional safety measures. If
there is, well, you'll need someone with one of these gates to tell you
what the hell to do. But you knew that. ;-)

This thing doesn't need to be very complex...the "up" switch should just go
to a "solenoid" (automotive term for "heavy duty power relay") that runs
the pump. The "down" switch should just connect to a small pressure
release solenoid that lets fluid out of the system and back into the
reservoir. When my Dad's fancy safety control circuitry gave up on one of
his he just replaced the whole mess with one switch (two direction, center
off). You run power to the middle of the switch. On one side run to the
"up" solenoid. On the other run to the "release" solenoid. Use a
momentary switch for safety and mount somewhere you can't easily bump it.
End of overly-aggressive safety mechanism, and probably far cheaper than
fixing it anyway.

I took my handy DMM to the thing and
discovered that the previous owner (or
his "repairman") had wired the release
solenoid to ground and the switch
control ground wire to the motor
solenoid. Bottom line, nothing was
wired where it was supposed to be. I
got all the wires where they need to be
and everything works great now.

If I hadn't discovered this newsgroup
and learned of Clay's manuals I would
never have developed the ability to
"logic out" simple wiring systems. I
feel so empowered. :-)

Thanks for the suggestion. I want to
put a breaker in but wasn't sure where
to get one (tried the local autoparts
stores). I'll check with our local
audiophile store.
