I have a Trailblazer 302, LJ050441Q. I am located on the Big Island of Hawaii. Service options are very limited here, requiring that it be shipped to Oahu and wait 10 weeks to get a repair estimate. The unit is low hours, but no longer under warrantee. I am looking for a service manual for this unit (not the owners manual-that is too limited). Either electronic or paper, willing to pay for it. I have a multimeter and scope meter and know how to use them.Just need more information to troubleshoot and repair.
