Wonder if Dave's parking light harness would assist getting current to the turn signals. Right front TS is still out, suspect corrosion in the electrical part of the switch, the little white plastic thing. I took one apart before, would rather not do it again since it's sort of fragile.

Already cleaned the contacts in the stock harness, the parking light sockets, and the hazard switch. The parking lights, hazard lights and the other turn signals are all OK. Getting voltage for that TS but not enough current.

It's a '73, built 9/72. Already have the headlight harness upgrade.

Oh, wait a minute. If it was corrosion in that electrical switch wouldn't it also affect the right rear TS? The little teeter-totter switch in there just has three positions, left, right and off.

No, it won't. They are separate circuits.

Are you talking about the switch or the electrical connector? Either way, Dave or I can clean/fix either of those. I even documented cleaning/repairing the switch. Turn Signal Repair | Fiddling With Z Cars

Not necessarily. The circuits are isolated between the front & rear. See this link: Hazard Switch ? Brake Light ? Turn Signal Circuit Analysis | Fiddling With Z Cars.

Stanley, I had the same problem of no right front turn signal and found this problem:

The die cast center section of the switch holds the lever and couples to the nylon slide on the bottom. On the top of the part, a pivot pin is press fitted into die cast and passed through the return spring. The other end of the pivot pin rests in the top stamping of switch.

In my switch the press fit between the pivot pin and die cast part had worked loose allowing slop in the joint coupling the nylon slide. This allowed enough free play in the switch pin so that passenger side did not make contact. Also 40 years of age allowed the nylon part to lose water and shrink, aggravating the situation.

I inserted a 0.050" thick washer between the switch and nylon slide for some relief. However the free play at the press fit still allowed excessive slop. I solved this by adding a 0.015" thick wave spring washer on the pivot pin under the top stamping. (If you follow my example, try not to disturb the return spring). The additional spring removed the axial free play that allowed the slop in the press fit. The turn signal action is like new and dirty contacts no longer appear to be an issue.

I purchased a '68 510 coupe and a '70 510 wagon new. Both had the same turn signal switch. After inserting the 0.015" washer, the action felt exactly the same as the 510's. The loosy-goosy action on the 240 is now only a memory.

Thank's, I'll study the links and photos before I do anything. My Combo switch is a used one, the lever is looser than the previous one so maybe that's it.
