Also if the battery voltage is low due to a failing cell? the engine ECU will increase engine speed to ensure there is sufficient output from the alternator!!
another nodge-wise gem of information .. good to know
~~~
.. and can I leave the relay out
well .. IF it is the ptc-heater relay your on about ..
it won't do any harm ..
just means the ptc-heater won't operate 'n provide cab heat before the engine coolant temp rises ..
( or 'add-to' the heat generated by the engine coolant )
on the plus side .. it won't add more work for the battery/alternator ..
not to have immediate cab heat doesn't bother me ..
but it might bother some folk i guess ..
for some reason i don't have misting window problems that some have ..
'n besides i often have the drivers window wide open even on the coldest of days .. at slow road speed
although .. without the ptc .. in sub freezing weather .. the in cab heat output does struggle a tad ..
i've a 'commercial' td4 hippo ( no rear side windows ) .. and a 3/4 height 'curtain' over the loadspace cage
so maybe more heats gets retained in the cab area than with a regular vehicle .. (?)

the ptc-heater relay .. they name as "R6" .. ( haynes manual names it as 'R13' for some reason )
