PARTS + SUPPLIES

Interstate MTP-24F Flooded Battery

Part no. MTP-24F

Used in Battery Test, Battery

How to check fit Example only. Match BCI group size, terminal layout and polarity, case size and at least the original CCA. Interstate lists the MTP-24F as group 24F, 750 CCA, top terminals, 10 3/4 x 6 7/8 x 9 7/16 in (273 x 175 x 240 mm). It is a flooded battery, so it is not a swap for a start-stop car that calls for AGM or EFB.

Bussmann automotive mini blade fuse assortment kit

Part no. Match the fuse type and amp rating printed on the fuse cover or old fuse

Used in Fuses + Relay

How to check fit Mini blade fuses are common, but I confirm the style and amperage in the owner's manual or on the fuse cover. I use the same size and rating, never higher. Bussmann's lookup tool is at the link.

Bosch Mini Relay

Part no. Match the number on the old relay

Used in Fuses + Relay, Starter

How to check fit Relays are vehicle-specific. I match the number printed on the old relay, or the one in the owner's manual fuse chart, plus the pin layout and socket shape. Bosch lists 0 986 332 040 as a 12 V, 4-pin mini relay, but its cross-references are mostly European, so I don't treat it as a North American starter-relay fit.

Part no. MM325

Used in Battery Test, Charging Check, Starter
