Frequently Asked Questions
💡 How does this tester protect the vehicle's electrical system?
You remove the vehicle's original fuse and insert it directly into the side fuse socket built into the tester's plug. This maintains the manufacturer-intended level of electrical protection during diagnostic testing.
💡 Can I use this current tester continuously?
No. To avoid circuit load strain, the tester has a maximum load rating of 20A / 48V DC for a maximum of 10 seconds. Always power off the vehicle's ignition switch prior to connecting or disconnecting the tester.
💡 Does this product arrive with the battery included?
No, the battery is not included. The current tester requires one 23A 12V battery, which must be sourced separately.
