Oiwa Garage Tech Note
"If a fresh main fuse blows again, find the short before fitting another - a repeat blow means a fault, not a weak fuse. Fit the correct amperage only."
Frequently Asked Questions
What amperage is this?
It is a 45 amp main fuse. Match the rating to your truck exactly - do not fit a higher amperage.
How do I test the main fuse?
Pull it and check continuity with a meter, or look through it for a broken link. If a fresh fuse blows again, find the short before fitting another - a repeat blow is a fault, not a weak fuse.
Can I fit a higher-amp fuse?
No. Fit only the correct 45 amp rating. A higher amp fuse defeats the protection, and a repeat blow means a short to find, not a weak fuse.
