Fusable link is just that, a piece of thinner wire that that melts when too much power goes through it for too long.
Please don't tell me some numb nuts elsewhere suggested to replace the fuseable link ( fuse ) on the FH 611V engine.
If the engine cranks then it is fine because it is a fuse .
It is also in a totally different circuit and will in no way shape or form affect either the cranking of the engine or firing of the ignition as it is part of the charging circuit.
Testing these units is a PIA and way too complicated to simply talk you through.
So below is the proceedure for testing the ignition components.
The spark tester they use is the sliding electrode type which a a little pricey but you can do a work around bu putting two wire inside a clear biro tube and moving then further apart .
Just note the warning about the maximum distance you can move them apart.
print it out. read it then if there is something you do not understand, get back to us.
