fitting 2nd battery D1 series 1 300tdi

<< < (2/3) > >>

Disco Matt:
Check the glow plugs. Mine was very reluctant to fire in cold weather, I later found that three of the plugs weren't working. It now starts within half a turn from cold regardless of conditions.

Range Rover Blues:
The 300TDi should have a short hose to suck air from behind the wing where the air is colder.  From around 1995 some models no longer had it fitted but the V8 trumpet is too much of a restrcition for a TDi.  You want a fairly blunt bell mouth though not just a cut-off bit of pipe.  Alternatively lots of 2" holes in the bottom half of the airbox.

Saffy:
Disco has started with half turn all this week with both battery fitted, no issues what so ever. Thinking maybe it worth replacing original earth strap and fitting an extra strap to starter motor and trying it with the single battery again next week. The battery is new and 570CCA 072 which should have been fine.

Range Rover Blues:
When I fitted a twin battery to my sister's RRC 300 I left the original battery in place connected to the starter and fitted a leisure batt on the LHS connected to the electrics, alternator etc with e 100 amp relay charging the starter battery .  It now starts fine so it seems the battery was getting drianed by the alarm.  So succesful was it that i fitted a split charge to Blue which now starts better on 1 battery that stays fully charged than it did on 2 that were flat all the time.
