## Questions & Answers

**Q: Can I use a smaller fuse?**
A: Yes, you totally can.  The overall load through the circuit should be about 80% of the rating of the fuse.  Hope this helps.

**Q: is the fuse for output power to the accessory ?**
A: The fuse is protecting the source voltage supply on the #30 terminal. In theory this also protests the accessory wired to the #87 terminal because if the source sees a spike and blows the fuse the output will not see any current. To be safe you can also fuse anything connected to the accessory side of the relay on the #87 terminal independently.

**Q: I have two 18w led aux lights hooked up to ome of these and its jimped into my parking lights. Why is ut buzzing?**
A: The only thing i can think is the holding coil. Do the lights flicker

**Q: These relays have built -in peak suppression diode?**
A: No, these relays do not have built in flyback diodes.
