Hello, I’m pretty new to this website. I have a 1985 M1028. Recently I’ve had to crank my truck a lot before start up. Even give gas while trying to start up to get it to fire. I can hear the relay click on and off. It does this multiple times, clinking on then a couple seconds later clicking off. The voltmeter doesn’t show any changes when the relay clicks on, when it used to show the draw. I love this truck, been great for me at school and want to get this figured out so I can have my daily driver back. Thank you for any help!
