TV Reception Woes

[Marion(57 Loboy)]

Pamela informs me that anytime I have the Loboy running, the TV picture goes all haywire. I have an antenna 30ft off the ground in the backyard next to the shed, wires run down the tower and then 4" in the ground over to the house. It has to be the ignition I think, any way to remedy this?

Replace your plugs with a resister type plugs. Resister plugs will have an R in the plug number.

you can use resistor plug wires also if you have a distributor, not a magneto

If your download to tv is twin lead instead of coax switch to coax (rg 6 ) that will help also . P/m me if you need more info.

RG-6 is what is out there.

Hi,
I asked my Case IH dealer about this same thing, interference from the ignition when the engine is running. This was just a few years ago. The parts man I know there has been there since 1978. That's when they were still IH, I think. He knows a lot about IH products. He said do not use resistor wires, put on regular solid core wires, and don't use resistor spark plugs. The ignition system was not made to use resistor wires or spark plugs, and the points will have problems if you put on resistor wires or spark plugs. The points metal will transfer from one point to the other is what happens if you use resistor wires or spark plugs. It makes a point sticking out on one point, and a matching hole in the other point.
I would say you will have to live with the interference the Cub makes. But you can put on different wires or spark plugs if you want. Thought I'd post what my local dealer said about it.

Another good way to remedy this is to just bring loboy here to me in Minerva, Ill bet you'll have a good picture then...

There is also a possibility that the generator is causing (or at least adding to) the problem. As an experiment, try taking the generator belt off (you can tie it back, away from the fan). See what running the tractor does to the TV that way. If it makes a big difference, try cleaning the commutator in the generator and installing new brushes.

By the way, rapid material transfer on the points as Glen described is usually the result of the capacitance of the condenser being off. Too much causes transfer one way, to little causes transfer the other way. Usually this is fixed by simply installing a new condenser. If that had been done with no improvement, something else in the system is off balance. I suppose the resistor wires could cause it. In that case, one could experiment with some non-standard condensers.

Probably way off on this, but. . .

is there power to the building with the antenna. A lot of RF is collected on current lines. a simple toroidal ferrite choke on the TV cord may help if this is the case.

rotor cables may also be the culprit.

I suggest contacting your local radio amateur club. Someone there may be bored and want a challenge. They can be found through the ARRL website.

Does it only happen when running in shed, or anytime close to house? Does the shed have metal siding? Does the antenna have a ground at the shed? I assume you are talking about broadcast tv, and not satellite.

Check your coax shield to ground connection. It should only be connected at 1 end.

Seems to me that when YOU watch the TV all is well. Whats the issue?

Could it be time for another cub?
Your wife could help to do the testing to compare the TV reception with each one...........

If the tractor is putting out that strong of an RF signal, I would be wrapping all my important places with tinfoil to keep them from getting microwaved while I drove the tractor.

I could see it if the tractor were parked with the distributor against the antenna mast, maybe... But it sounds like this is happening any time the tractor is running? Even around the yard?

That's a pretty strong signal to be throwing off.
