1984 Chieftain not cranking

[tiinytina]

You may have a blown ignition control module... this will completely kill power to ignition etc... its under the distributor cap and rotor...  flat plastic about 2" long with connectors both ends.. make sure you reinstall new one with the electric grease stuff under it...  when this little part goes there is no crank, no click no nothing and when it dies so does the engine if on at the time (twice happened)...

I think I am having the same issue but I cannot get my 82 Chieftain P30/454 start to chrank.  Here is what I have.  No horn, no headlights, no start, no starter cranking.  NO power to the starter relay (same picture as above).  I have traced the 12v cable from the battery to the fuse block (behind radio) and I have 12v going to the fuse block and all fuses have been checked.  Some more information.  I did hook up a tachometer with +/- and one to the tach side of the distributor.  So after reading this last entry I am thinking it may be the Ignition Control Module.  But how does this control the power to the starter relay??  Any input would help.  and thank you for reading.

Re-reading this post.  There must be a fusible link down on the starter that runs up the starter solenoid.  There is a fusible link coming off the solenoid that is working.

Could a bad ground cause it??

It kind of sounds like the fusible like on the starter that you described although that should be controlling more items. It is possible that Winnebago has bypassed the fusible link for some of this stuff though so be sure to check the link. Also be sure to remove, clean and replace both the hot wire on th starter and the ground wire on the frame and on the engine. These can get dirty and pass enough power for low voltage stuff but will not power a starter.
