The safety switch is located on the underside of the tractor and is engaged by a metal tab on the brake linkage.\u00a0 There is an orange wire that runs from the ignition switch to one of the safety switch terminals.\u00a0 There’s an orange\/black wire that runs from the safety switch to the starter solenoid.\u00a0\u00a0 The easiest check is to use your voltmeter to check the voltage at the solenoid terminal.\u00a0 If you place the positive lead on the solenoid terminal (it’s the smallest of the three terminals on the solenoid)\u00a0 and ground the negative lead you should read 12 volts when you move the key to the start position with the brake terminal depressed.\u00a0 The problem is that if you don’t get 12 volts, it could be a bad connection or bad ignition switch.<\/p>\n
To isolate the problem to this section of the wiring, I generally use a jumper wire to apply voltage to the solenoid.\u00a0 They’ll be one large wire (usually red) that runs from the postive terminal on the battery to one terminal on the solenoid.<\/p>\n

<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n (The three pictures above are starter solenoids.\u00a0 The two pictures on the right are of the same solenoid, just different views.\u00a0 Notice the two large terminals and one smaller terminal on each of the solenoids.\u00a0 When power is supplied to the smaller terminal it makes an internal connection between the two larger terminals supplying voltage to the starter. On narrow frame Cub Cadets the starter solenoid is generally located behind the battery on the left side of the pedstal when facing towards the back of the tractor.)<\/p>\n <\/p>\n Take a small jumper wire and touch one end to the terminal with the red wire and the other end to the small solenoid terminal.\u00a0 The engine should crank over even with the ignition key in the off position. Don’t run a jumper wire between the two large terminals unless you have a heavy wire like in jumper cables.\u00a0 This connection involves very high currents and would overheat a small wire and cause a fire.<\/p>\n If the engine cranks over with this test, you have a problem somewhere between the ignition switch and the solenoid.\u00a0 I would next place a jumper across the safety switch terminals.\u00a0 If this corrects the problem, you have a bad safety switch or corroded connections.\u00a0 If it doesn’t correct the problem, you probably have a bad ignition switch or corroded terminals on the ignition switch.<\/p>\n If the engine doesn’t crank over with the jumper across the solenoid, you may have a bad solenoid or a bad connection.\u00a0 I generally check this problem by using a jumper cable (again, no small wire) to jump from the positive terminal of the battery to the armature terminal of the starter\/generator.\u00a0 If the engine doesn’t crank with this test, the starter\/generator may not be properly grounded.\u00a0 Check this connection by running a jumper cable from the negative terminal of the battery to the frame of the starter\/generator.\u00a0 If the engine still fails to crank, I would suspect a bad starer\/generator.<\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" If the engine doesn’t crank and the battery checks good, you have a weak or broken connection.\u00a0 Generally the first thing to check in this situation is the safety switch.\u00a0 All the narrow frame Cub Cadets with the exception of the Original, Model 70 and Model 100 came equipped with a safety switch that prevented […]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2}},"categories":[33],"tags":[],"class_list":["post-1201","post","type-post","status-publish","format-standard","hentry","category-doesnt-crank"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"","jetpack_shortlink":"https:\/\/wp.me\/p4lT6g-jn","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/cubcadetman.com\/cc\/wp-json\/wp\/v2\/posts\/1201","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cubcadetman.com\/cc\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/cubcadetman.com\/cc\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/cubcadetman.com\/cc\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/cubcadetman.com\/cc\/wp-json\/wp\/v2\/comments?post=1201"}],"version-history":[{"count":2,"href":"https:\/\/cubcadetman.com\/cc\/wp-json\/wp\/v2\/posts\/1201\/revisions"}],"predecessor-version":[{"id":1206,"href":"https:\/\/cubcadetman.com\/cc\/wp-json\/wp\/v2\/posts\/1201\/revisions\/1206"}],"wp:attachment":[{"href":"https:\/\/cubcadetman.com\/cc\/wp-json\/wp\/v2\/media?parent=1201"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/cubcadetman.com\/cc\/wp-json\/wp\/v2\/categories?post=1201"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/cubcadetman.com\/cc\/wp-json\/wp\/v2\/tags?post=1201"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"connections](\"https:\/\/cubcadetman.com\/cc\/wp-content\/uploads\/2014\/03\/connections-pic-1.jpg\")
