Two German cars

The lead battery has problem on XH200 OPEL B-Vectra recently, there may be some dark current, lack of charging capability or starter motor armature or brush dysfunction?

However hard I may inspect the circuitry I couldn't find out any short cut tendency, the resistance value was enough.

The connection on the plus terminal on the alternator with battery must be reconstructed additionally, not yet.

The wiring from battery plus terminal to starter motor supply is not checked yet.

This kind of car trouble has no way to be grasping and has some tendency to be protracted, so the effort to be solved sooner is the better way, try to wipe out any bad feeling like this!

As an experimental trial, D type battery was applied on the standard European style battery space with the condition that the terminals are same size on plus and minus terminals promptly, GM- X20 motor started immediately without any hesitating reactions.

On the other hand, as for air-cooled VW 1302 Super Beetle:
The inconvenience caused by the lack of the thermostat function is difficult to be compensated by extending the time period of automatic choke heater's action.

Over cooling phenomena cannot be compensated without shutting the flaps mechanically by the thermostat activation.
Basically the inconvenience caused by the dysfunction of the specific device cannot be compensated by another method, being essentially impossible.

Then, how about looking for the thermostat parts, though I have never come across this parts in the Web site?
