Hey I have a 56 voyager. It's been a bit iffy to start for a while. Last night it decided that it wudnt start and I'm getting nothing when I turn the key.ive tested the battery and that's fine and I'm getting lights etc.i checked the selonoid on the starter by running a wire from the battery to the starter and it still isn't starting. My dash needles go mental when I turn the key. Any ideas on what to do? Does it sound like I need a new starter etc
