              (and, advice needed...) (was: Re: low voltage,
              starter running intermittently, but alternator is okay?)

Are you sure it is the starter solonoid clicking? I think relays can chatter too,with a bad connection. If you hot wire at the starter, you will bypass all the wiring from the key to the starter(except the large starter cable).If it starts every time doing this, the problem is in your wiring between the solonoid and the ignition switch.If it acts the same as before (1 start in 10), that wiring and ignition switch are ok.If you do this and the problem remains,either you have a bad solonoid, a bad starter moter, a bad starter motor housing,a bad battery connection from the starter to the battery, or your starter motor is not grounding to the bell housing(you need this last posability so you get a completed electrical circut) .The solonoid is a coil of copper wire that becomes an electro magnet.Turning the key to the crank position energizes this coil so it is a magnet.Releasing the key to the run position turns this magnet off,and the starter gear returns to its normal position(disengaged),and current to the starter moter proper,is cut off too.Both run and start positions of the key, allow current to get to the ignition(spark plugs). The electro magnet controls two functions when engaged.First , it engages the starter gear with the flywheel. Second, it allows connection of the heavy wire from the battery,with the starter moter proper(not the solioid).When in the run position you get a direct,heavy current to turn the starter through the big cable.There is a yoke inside the starter that pivots to make these two operations,decribed above, succeed. If the starter moter housing has mechanical issues such as binding or hanging up, the gear will not engage and the heavy current will not flow.You can check it somewhat by removing the starter and physically prying on the gear to see if it operates smoothly.The solonoid is an electrical item ,so any warrenty is dubious. Lots of issues can take place to make a solonoid inoperative.Low current to the solonoid causes it to clik, or chatter. Not enough current to hold the internal contacts, down, and the contacts make noise.. There is about 1 mile of copper wire inside the coil. If it breaks or the insulation goes bad, The coil/solinoid is toast.This is not your problem, as the coil energizes 1 in 10 times. If the coil wire is broken it will most likely notain.The coil is shaped like a donut. When energized, a plunger that goes through this hole is "moved."Like in elementry school when you did electromagnet experiments. The plunger is attached to a yoke that makes the heavy current engage.It is very hard to make regular switches for heavy currents , so they all do it this "manuel" way, .It is like a see saw. The magnet pulls one side of the see saw down and the other side goes up and engages the heavy current.If this binds, the car wont start.You can hear the slamming of the yoke when solonoid current is engaged.Disconnect the heavy wire to the starter to keep the area quiet, and listen for this slamming to see if the starter mechanics are smooth and bind free.Remember, that this noise is not the clicking of the solonoid.It is a different noise.The starter must be bolted tightly and without insulating grease between it and the bellhousing. This, for good electrical conductivity.Should not ever have a problem here.So, it seems that the problem is most likley the starter moter,but you need to eliminate the wiring and ignition switch as the problem. Do this by hot wiring at the starter solonoid. I did this once, but I cannot remember which terminals I used.So sorry here.You want to energize the coil, and provide current supply to the ignition(so it will start).Current supply to the ignition originates from a connection at the starter. This wire goes somewhere to an ignition component.You want to jumper the ignition terminal tobattery power.Thiswont crank the engine though. Next, you need to jumpper from that same battery source,tothe solinoid coil.Like I say, I havent done this in a couple years,so the bentley needs tobe opened up for specific connections.Not hard to do.Let us know the results.
