Wow, this subject keeps cropping up!
I think putting ANOTHER relay in the starting circuit (even though it appears to solve the problem for everyone that tries it) is absurd.The starter solenoid is indeed a relay whose power contacts put power to the starter motor and whose movement also throws the starter's drive pinion gear to mesh with the engine flywheel.Having to install a SECOND relay, because the connections, ignition switch and wiring to the coil of the starter solonoid are inadequate or unreliable simply masks a problem that may get bad enough to re-occur someday, or cause another highly unsafee incident of non-starting if the (previously non-existent) newly installed component fails of it's own accord at some point.I rewired the circuit on my Hunter 30 with the appropriate 12 gage wire, a new key switch from WM and eliminated all slip type connections except the one right at the solenoid coil (which I doused with acid flux, covered with a nice small blob of electronic solder and covered with shrink tube). Just half the summer so far but the thing hasn't yet acted up.PS 4 years ago, before I did this work and had to deal with the possibility of a noiseless ignition attempt, I made up a little "if all else fails" tool. A big sccrew driver with a 3" long bent piece of copper bar brazed on the end of it that I could gingerly reach in and jump 12V right to the starter motor while my wife was turning the key.That NEVER failed. I've had to use it only twice, and I had to contend with some arc damage on the threads of the power wire lug bolts, and the general anxiety of this unsafe method, but it sure was better then always starting my engine way before I really had to and that sick feeling of the "what if" very unsafe scenarios that kept replaying though my head when I knew my engine's ability to start was questionable.
