The fuseable link is that - it is the "fuse". Pull on each end of the wire of the link which is usually 3 to 6 inches in length to see if the wire stretches for if it does then the link has separated in side of the sheathing.

"also no fuse on fusible link"

I think you are confused as to what a fusible link is. There is no fuse ON it. The Link IS the fuse. It is designed to burn out similar to a regular fuse, but it is more resistant to short duration overloads.

They are supposed to stretch out and the insulation to look burnt when they have blown.
When Mine blew it did neither.

Get a partner and fondle, bend and twist the fusible link with the engine running( do not touch the body of the van with your body when doing this, possible zap), you should be able to hear the engine note change as continuity is made and lost. The voltmeter should swing as well.

Another thing to check, Follow the smaller wires from the alternator to the PCM/ECM/SMEC. A loose connection on that wire will also cause the "bump and work temporarily" scenario, and a check engine light.

When my ('89)fusible link was blown, there was no check engine light.
Good luck, post back.

Alloro,

Do you also bust out the
"That's what she said!" jokes?

Fusible links need attention too.
Even if they're fat and designed for more punishment and handle more load for longer than your standard skinny blade type fuses.
