I expected to find a loose wire or failed bulb.&nbsp; Neither of these <g class=\"gr_ gr_65 gr-alert sel gr_gramm gr_replaced gr_inline_cards gr_disable_anim_appear Grammar multiReplace\" id=\"65\" data-gr-id=\"65\">was<\/g> the case.<\/p>\n\n\n\n<p>I then decide to check the fuses and after searching the inside of the fuse box and several internet searches, I could not find a listing for the tail light fuse.&nbsp;&nbsp; I read through a couple of forums and still no mention of a tail light fuse.<\/p>\n\n\n\n<p>So next I printed out the wiring diagrams.&nbsp; These are hard for me to follow but even more so in that<g class=\"gr_ gr_167 gr-alert sel gr_gramm gr_replaced gr_inline_cards gr_disable_anim_appear Punctuation only-ins replaceWithoutSep\" id=\"167\" data-gr-id=\"167\">,<\/g> the individual bulb functions are not listed on the diagram.&nbsp; It shows all the bulbs in the tail light housing but not what each one does.<\/p>\n\n\n\n<p>So I pulled the tail lamp assemblies apart and traced the wires from the non-functioning bulbs to the connector and determined the wire color on the harness side fo the connector.&nbsp; That is when I noticed that a previous owner had redone the wiring so that the left side tail light was jumpered to the right side taillight. I found that odd but continued.<\/p>\n\n\n\n<p>I finally figured out that the tail light bulbs also power the side markers. I don&#8217;t have side markers on the race car but I do still have the plugs dangling from the tail light housings.&nbsp; I remembered seeing a side marker fuse listed when I was researching.<\/p>\n\n\n\n<p>So fuse 40 and 41 are listed for the side markers.&nbsp; Sure enough, both these fuses were blown. I tried replacing fuse 40 and it would instantly pop indicating a dead short.&nbsp; Fuse 41 seem loose.<\/p>\n\n\n\n<p>After tracing the wiring diagram again, I figured out why the previous owner had jumpered the two tail lights together.&nbsp; The left <g class=\"gr_ gr_146 gr-alert sel gr_spell gr_replaced gr_inline_cards gr_disable_anim_appear ContextualSpelling ins-del\" id=\"146\" data-gr-id=\"146\">side<\/g> marker circuit has a dead short.&nbsp; So he powered the left side off the right side. <\/p>\n\n\n\n<p>I then replaced the fuse for the right side marker circuit and wiggled it around to get it to seat properly.&nbsp; After some wiggling of connectors in the rear of the <g class=\"gr_ gr_69 gr-alert sel gr_spell gr_replaced gr_inline_cards gr_disable_anim_appear ContextualSpelling ins-del multiReplace\" id=\"69\" data-gr-id=\"69\">car<\/g> again had tail lights on both sides. <\/p>\n\n\n\n<p>I will later go back and see if I can locate the short in the left <g class=\"gr_ gr_147 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar only-ins replaceWithoutSep\" id=\"147\" data-gr-id=\"147\">side<\/g> circuit. I expect this is why my left front marker has never worked. <\/p>\n\n\n\n<p>Update:&nbsp; I found the short:&nbsp;\/<a href=\"http:\/\/mikestrawbridge.com\/blog\/2018\/10\/short-finder-tool\/\">http:\/\/mikestrawbridge.com\/blog\/2018\/10\/short-finder-tool\/<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Repairing my 944 tail lights &#8211; Tail light fuse late 944 After my last trip to AMP for track night, I ended up having to drive my race car home due to a tow vehicle failure.&nbsp; Halfway home, I stopped to eat and noticed the tail lights were not working.&nbsp; However, I had two very &hellip; <\/p>\n<p class=\"link-more\"><a href=\"http:\/\/mikestrawbridge.com\/blog\/2018\/10\/944-tail-lights-dont-work\/\" class=\"more-link\">Continue reading<span class=\"screen-reader-text\"> &#8220;944 Tail lights don&#8217;t work&#8221;<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[542,210,513,530,1],"tags":[510],"_links":{"self":[{"href":"http:\/\/mikestrawbridge.com\/blog\/wp-json\/wp\/v2\/posts\/4385"}],"collection":[{"href":"http:\/\/mikestrawbridge.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/mikestrawbridge.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/mikestrawbridge.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/mikestrawbridge.com\/blog\/wp-json\/wp\/v2\/comments?post=4385"}],"version-history":[{"count":4,"href":"http:\/\/mikestrawbridge.com\/blog\/wp-json\/wp\/v2\/posts\/4385\/revisions"}],"predecessor-version":[{"id":4494,"href":"http:\/\/mikestrawbridge.com\/blog\/wp-json\/wp\/v2\/posts\/4385\/revisions\/4494"}],"wp:attachment":[{"href":"http:\/\/mikestrawbridge.com\/blog\/wp-json\/wp\/v2\/media?parent=4385"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/mikestrawbridge.com\/blog\/wp-json\/wp\/v2\/categories?post=4385"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/mikestrawbridge.com\/blog\/wp-json\/wp\/v2\/tags?post=4385"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
