Question about Olympus OM-4TI 35mm SLR Camera
Film advance on your model is entirely mechanical and is not affected by the batteries, but it does interlock with the shutter mechanism which is entirely battery dependent.
Unfortunately, OM4's are were notorious for having a main circuit board which corroded. There were a number of revisions to the board and the OM4-ti had a major revision which improved things greatly but didn't fix it entirely. If the board's faulty, your camera has become a display piece only as it cannot be fixed and spares are impossible to obtain. It doesn't help that OM4-ti's were made in far fewer numbers than regular OM4's and that the boards are not interchangeable between them.
It is still possible though that the fault is due to the camera just needing a thorough CLA service (Clean, Lubricate, Adjust) but expect to find that some mechanical parts may need to be replaced, especially if the film advance has been forced. If the shutter assembly is faulty, then once again you're into rocking-horse poo territory as it's unique to the OM4-ti. They can't be obtained new any more, but they can be taken from scrap OM4-ti's which suffered circuit board failure.
Note that due to the complexity of this model most repairs are not a DIY option. Repairs will not be cheap, but an OM4-ti which is advertised for sale with proof of recent professional repairs and servicing by an Olympus specialist is worth a lot of money so is often a worthwhile investment.

I have been servicing Olympus OM cameras since 1977. If yours is a mechanical problem, it can be fixed. All 4T/Ti boards are low battery drain and are the desirable version. Older OM-4 may have the original high drain circuit board, or one of two intermediate boards Olympus released featuring lower battery drain. The original OM-4 did not have a problem with "corroding" circuit boards. The last 2 OM-4 bodies I saw (that were donated to me for parts) had paperwork with them (from another repair shop) suggesting they were beyond repair due to "corrosion". Sure, one was thoroughly dunked in the ocean, and the other had 3 in 1 Oil squirted into it (though theoretically that would stop corrosion and cause it's own problems). John
