boxboy Posted January 14, 2012 Report Share Posted January 14, 2012 I have an ignition switch that is going out on me. If you don't let it "bounce back" after starting, and just easy let go of it, it works fine. But, if I just start it and let go normally it seems to turn back a bit too far and kill the engine. I have also notice putting it in the "on" position that sometimes the ALT/OIL lights don't go on unless I move the key a bit one way or the other. The wires to the starter seem fine. Is there any way to fix this, or am I doomed to replace the start switch with a generic? It is still the orig. switch from 1968 as far as I can tell. I'd like to keep it that way. 1 Quote Link to comment

boxboy Posted January 15, 2012 Author Report Share Posted January 15, 2012 WD 40????? get anonther they cheap The problem is I believe the 520 is a different switch than the 521, and I don't see them available anywhere. It would be nice to keep my keys matching the door locks too. I don't think WD is the trick. It's not sticky at all, if anything it is just too loose. Quote Link to comment
420n620 Posted January 15, 2012 Report Share Posted January 15, 2012 mklotz did a write up on the 521 ign switch, should also work for the 520. http://community.ratsun.net/topic/37977-521-ignition-switch-disassembly-mklotz70/ http://www.bluehandsinc.com/ignition-switch.html Quote Link to comment
bananahamuck Posted January 18, 2012 Report Share Posted January 18, 2012 Never mind................. i didn`t notice you were working on a 520....not 510 Quote Link to comment
boxboy Posted January 27, 2012 Author Report Share Posted January 27, 2012 Okay, this is a question to the sages of this forum. The 620 switches are cheap and available. The 521/520 switches cost $50 up to $80. Will the 620 switch fit physically and wire up with a three wire set up, or am I screwed? Quote Link to comment
Guest LoneWolf Posted October 5, 2012 Report Share Posted October 5, 2012 I have an key ignition problem again on my 1972 510...I don't want to change the whole key ignition assembly again...so my question would be who is running a completely different type of key ignition for their 510? I don't want to be "pick starting" my car everyday...when I change the ignition its perfect for about 2 months and then the ignition gets "gimpy" again. Quote Link to comment
izzo Posted October 5, 2012 Report Share Posted October 5, 2012 my 620 had a key start in the dash board. the lighter was removed and a standard ignition was used. It was beefy as all fuck, off summit racing. I might have it somewhere still but doubt it. This one was four post Quote Link to comment
