SPM-HEP-4704 is the 24 volt battery (main power) relay with a steel can, copper stud terminals, a mounting bracket with cream insulators and a sleeved harness with plugs. It is used on Kobelco SK200-8 and SK200-6E excavators. This aftermarket version has the same mounting and electrical connector as the original, so it plugs in and bolts on where the old one came off.
It replaces Kobelco YN24S00003F1 and Kobelco YN24S00008F1.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Applications & use cases
Function dead with good fuses
A starter, glow plug or fuel relay that has burned its contacts stops the circuit without blowing a fuse.
Clicking but no power
A relay that clicks but does not pass current has worn contacts and needs replacing.
Heat and vibration
Relays near the engine wear out from heat and vibration. Swap them during major services.
Fleet spares
Relays are cheap to keep on the van and quick to change on site.

Frequently asked questions
Will it fit my Kobelco SK200-8?
Yes, it was made for the Kobelco SK200-8, and 3 more listed under compatible equipment. Check the old relay is marked YN24S00003F1 or one of the cross references, because makers change parts between serial ranges.
How often should I replace the relay on my Kobelco SK200-8?
On the Kobelco SK200-8, there is no fixed interval. It is changed when it fails, and many fail from water in the plug or chafed wiring rather than wear.
What are the signs the relay needs replacing?
A fault code for this circuit, readings that jump or stay fixed, or a part that does not respond with power at the plug.
Do the fault codes need clearing?
Usually. Clear them after fitting and run the machine, so old codes are not mistaken for a new fault.
Should I grease the connector?
A little dielectric grease keeps water out of the plug on machines that work outside. Make sure the terminals are clean and tight first.
Is this a genuine Kobelco YN24S00003F1?
No. It is an aftermarket relay made to replace the Kobelco YN24S00003F1. It is not made by the original manufacturer; the number only shows what it replaces.
