rwilson 128 #1 Posted August 21, 2013 This is for all you tecumseh guru's out there. I have a tecumseh 6hp that does not have a charging system in it. My Lawn Ranger is the electric start model. I am wondering if I can put a stater under the flywheel and if I need anything else to make it work? Do I need the "Diode" block or can I use a regular old Rectifier/regulator? Any help would be great. thanks. Share this post Link to post Share on other sites

rmaynard 15,675 #3 Posted September 2, 2013 I have a Tecumseh V70 with electric start on a '70 Lawn Ranger that I am working on. I know nothing about it. But l do know that like the Kohlers, it has magnets on the underside of the flywheel, a magneto for the spark, and little coils to generate AC power. The AC leads go to a bank of rectifiers on the side of the engine. Here is a page from the Ranger owners manual. Hope this is some help to you. Share this post Link to post Share on other sites
rwilson 128 #4 Posted September 2, 2013 (edited) Does that rectifier block do the same thing as a regular regulator? Edited September 2, 2013 by rwilson Share this post Link to post Share on other sites
buckrancher 2,694 #5 Posted September 3, 2013 you will need the stator plate, flywheel ,diode block and wiring and keyswitch should be a bolt on as the h60's came with electric start also Share this post Link to post Share on other sites
SousaKerry 502 #6 Posted September 3, 2013 your best bet would be to find a junk motor with all the parts already. But as long as your shroud has the bump out for the starter you should be all set with the required parts. Be careful with selecting the flywheel as there are several different types used over the years. Later ones have an external magneto, flywheels with the correct magnets will only have magnets underneath, be solid cast iron, and the magnets go around the total circumference of the flywheel. If there are just 2 magnets then it does not have the charging magnets. Also watch out that the taper is the correct size some of the heavy duty engines used a larger crank journal and bigger nose taper. There are a lot of flywheels out there for sale that have a starter ring but no charging magnets, these were used on snowblowers with 120V start systems. I am actually running one of these on one of my tractors, since it has magneto ignition the battery doesn't discharge much and I only have to hook up a battery charger a couple of times a season. Charging Stators are getting hard to find in good condition. The charging version looks just like the non-charging one except it has a couple of coils wrapped around 2 more ears on the stator. A couple of the ones I found are rusted and starting to delaminate. The regulator boards are crap and it is almost impossible to find one with good original diodes. There have been many posts on this subject of how to build replacements and also a few posts on building a new circuit entirely. Just do a search on Tecumseh charging. Good luck hope I did not scare you away, these are just some of the problems I found out about the hard and expensive way.... 1 Share this post Link to post Share on other sites
rwilson 128 #7 Posted September 3, 2013 I'm not scared!! Bring it on!! I believe I have everything I need but my diode thing might be bad. I'll have to get hold of SOI to see how and test it. Share this post Link to post Share on other sites
