I have a 4905A - 8V71 w/4 speed Spicer. On finishing the starter replacement, I noticed that the last 2" or so of the insulation on the 24V+ cable from the batts is very dry and brittle. From 6" back it looks fine and the brittle section also looks like it's been re-insulated at least once before. The wire itself looks fine and the crimped connection is still in excellent shape. There is no evidence of corrosion on either the lug or bare cable. What has anyone used to re-insulate 4/0 cable in a high heat location such as this ? Many thanks

High voltage/high temp. splicing tape from the local electrical supply house. No, not Home Depot, go with the contractor's warehouse. Since it is clean, apply four (4) half-lapped layers, making sure that you extend upon to the good part of the insulation, and onto the lug itself.. Each layer should go a little further than the last one. Finish it off with two (2) half-lapped layers of Scotch 88 Vinyl electric tape. This will hold up, and have superior insulating qualities. HTH, and Cheers...JJ |

The 3M / Scotch 88 Vinyl electric tape is available at most Home Depots here in Florida, Home Depots birth state.
I personally prefer high temp heat shrink tubing.

Replacing the entire cable is undoubtedly the best way to go, but, if I remember correctly, the 4905's batteries are just behind the right front wheel. That's a lot of 4/0 wire and very expensive. An alternative is to slide a piece of heater hose or large fuel line over the brittle insulation and seal it in place with RTV silicone or even Sikaflex.

Several layers of heat shrink would probably be your best bet here. I just bought 30 ft of 4/0 welding cable and it cost me less than 80 bucks. |

Good heat shrink is great, it just won't be quite as Flxible. Just try to seal out moisture and oil, since they will start corrosion, which will degrade the ability of the cable to provide the proper amperage flow. BTW, the proper cable to replace it with is THW or THWN/THHN, not welding cable. Welding cable will do a fine job, BUT is not Code approved for the application (due to the distance involved, and because it is in a raceway. Why worry about he Code when there is no Inspector? Because your Insurance Carrier may decide to not pay off on a loss, if it does not meet "Standards" BTDT ...JJ |

I just checked what I paid for 4/0 battery cable wire, not welding cable, and it was $6.33 per foot. Needing around 30 ft for the 4905, it will be about $200 for the right wire with terminal ends. Re-insulating the existing wire sounds even better now.

You might want to check the volts AT the starter , while its turning.
IF its under 9 or 9.5V , under load , you will be needing new wire , or a fix someplace!
