    You (or an automotive electric specialist) can put an ammeter on each motor circuit and find out which one is overloaded. Then you can hopefully track down the source of the increased load. I think its more likely that the problem is a mechanical bind in the top mechanism somewhere than the motor itself. I'm not familiar with the cab top system, but if it has gearboxes, that's where I'd look first.

    This is just a hunch, but it sounds like an electric motor with a built-in thermal protection that works like a slow-blow fuse. Heats up from excess current (load); shuts off, then comers back when it cools in 15 minutes. I'd guess that either something in the top mechanism is binding and causing too much load on the motor and overheating it, or the motor itself has a problem.

    New member here. If I get favorable answers to my question I may get to be an old member. I was ready to pull the trigger on a lovely '99 996, but reading more and more about their random and common engine disintegration, I've backed off. I'm not too keen on driving a car with Russian roulette in its genes. The decision would be so much easier to deal with if there were some odds or stats based on real data. So PCNA has kept the data secret so no one really knows the failure stats? Considering how many Porsches are owned by lawyers, that's surprising....but that's a different subject. I read one post by a (supposed) authority saying that 1 in 5 996 engines become toast and need replacement? That's an appalling number. Scandalous. But 1 in 1000 would be no less appalling for production automobile by a maker who promotes its excellence in engineering! So my questions are: Is it true that the blown engine syndrome is a 3.4 issue? Are factory remanufactured engines immune to the random grenading? Are 2002 and later engines (3.6) immune? Is the IMS problem completely separate from the blown engine issue? Seems like the grenading is completely random and the owner can do nothing to prevent it. True? I fell for Porsche hard about two minutes into a test drive. These cars are like automotive crack. I hope I can rekindle the ardor, but when I see so many stories about $12-15K engine bills, I think the constant worry will outweigh the fun. Maybe you can talk me down.

    I imagine you've already run it, but after sitting for three months there's very little oil film left on wear surfaces, so I'd crank it for a short bit with no ignition to get the oil back where it belongs before firing it up.
