fusable link

Post by boogieman on Sat Jun 04, 2016 4:08 pm

ok, 1968 g10 108 l6/250, hei, cs130 alternator, im using and inline atc 30amp fuse instead of a fusable link. well, it started blowing recently, start up and within 15 secs it will blow...installed a 30 circuit beaker to start tracking my problem and the circuit breaker doesnt trip...nothing seems to be getting hot near the circuit breaker..should i be using a higher amp fuse? maxi fuse? sloblo? alternator check out at pep boys, putting out 15.4v max, seemed a little high maybe..

The 14 gauge fusible link should be connected to the positive battery cable where it connects to the starter solenoid,,,,,,its slow acting, not like a fuse or circuit breaker,,,,which gives the van time to energize all the systems,,,,,,,,the alternator gets its information at the #2 terminal of its voltage regulator,,,,,,if that signal is low,,,,,it tells the alternator, put out more reguardless if the battery is full,,,,,so you got a couple of different things going on to check,,,,,,,

alt is putting out more amps than the fuse can handle, needs to be higher
than the alt out put in amperage. fuseable link with an 8 gauge wire from
starter to alt should get the job done, that is what I have on mine.

Fusible links monitor heat that a wire can safely carry,,,,,,,,you need the right one ,,,a 14 gauge link is the one for a 10 gauge wire,,,,and you want the link right where the Positive battery cable splits down to the smaller feed wire that feeds the truck,,,,,so that it cuts off the juice if something shorts out,,,,,the fuse block protects the other circuits in the system,,,,,,the fusible link protects the fuse box,,,,,, now if that 14 gauge fusible link blows,,,,,you,,,,,,,,,,got a problem somewhere,,,,,

I put a 40 amp one wire alt on my Goldwing using a 10 gauge wire
from battery with a 30 am fuse in a holder, and it kept blowing the
fuse when the cooling fan came on, replaced the wire with an 8 gauge and
a 50 amp fuse, no more issues, and charges great.
